Remarks

The SSLServer Class supports Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections. When connecting over Secure Sockets Layer/Transport Layer Security (SSL/TLS) the SSLServerAuthentication event allows you to check the server identity and other security attributes. The SSLStatus event provides information about the SSL handshake. Additional SSL-related settings are also supported through the Config method. The SSLCert properties are used to select a certificate for the server.

Note: A valid certificate MUST be selected before the server can function.

SSLServer is the server complement of SSLClient, which is used to create client applications. They share a common design philosophy and interface. We expect you will find SSLServer to be as easy to use as SSLClient.

By default, each instance of SSLServer can handle up to 1,000 simultaneous incoming connections. This number may be increased up to 100,000 or decreased to a lower value by using the MaxConnections configuration setting.

The connections are identified by a ConnectionId, an Id generated by the component to identify each connection. This Id is unique to each connection. SSLServer's events also include a ConnectionId as a parameter to identify the connection they relate to.

Our main goal in designing SSLServer was to make it easy to use without sacrificing performance. The class has a minimum of properties, and six events: ConnectionRequest, Connected, DataIn, Disconnected, ReadyToSend, and Error.

SSLServer can start to listen on a port by setting the Listening property to True. When a remote host asks for a connection, the ConnectionRequest event is fired. At that point, the connection can either be accepted or rejected. If the connection is accepted, a ConnectionId is assigned, and communication can start. From this point on, the operation is very similar to SSLClient. Data are sent by calling the Send method with Text as a parameter. The address and port of the incoming connection can be found by querying the RemoteHost and RemotePort properties.

Note: Server components are designed to process events as they occur. To ensure that events are processed in a timely manner, DoEvents should be called in a loop after the server is started.

This property indicates whether data reception is currently enabled.

Object Oriented Interface

public function getAcceptData($connectionid);

Procedural Interface

ipworksssl_sslserver_get($res, 3 , $connectionid);

Default Value

true

Remarks

This property indicates whether data reception is currently enabled. When false, data reception is disabled and the DataIn event will not fire for the connection. Use the PauseData and ProcessData methods to pause and resume data reception.

The $connectionid parameter specifies the index of the item in the array. The size of the array is controlled by the ConnectionCount property.

This property is read-only and not available at design time.

Data Type

Boolean

BytesSent Property (IPWorksSSL_SSLServer Class)

This property shows how many bytes were sent after calling Send or SendBytes .

Object Oriented Interface

public function getBytesSent($connectionid);

Procedural Interface

ipworksssl_sslserver_get($res, 4 , $connectionid);

Default Value

0

Remarks

This property shows how many bytes were sent after calling Send or SendBytes. Please see Send or SendBytes for more information.

Note: This property will always return 0 when the class is operating in the synchronous mode (i.e., the Timeout property is set to a positive value).

The $connectionid parameter specifies the index of the item in the array. The size of the array is controlled by the ConnectionCount property.

This property is read-only and not available at design time.

Data Type

Integer

Connected Property (IPWorksSSL_SSLServer Class)

This property indicates the status of individual connections.

Object Oriented Interface

public function getConnected($connectionid);

Procedural Interface

ipworksssl_sslserver_get($res, 5 , $connectionid);

Default Value

false

Remarks

This property indicates the status of individual connections.

When true, the connection is established. Use the Disconnect method to disconnect an existing connection.

The $connectionid parameter specifies the index of the item in the array. The size of the array is controlled by the ConnectionCount property.

This property is read-only and not available at design time.

Data Type

Boolean

ConnectionId Property (IPWorksSSL_SSLServer Class)

This property contains an identifier generated by the class to identify each connection.

Object Oriented Interface

public function getConnectionId($connectionid);

Procedural Interface

ipworksssl_sslserver_get($res, 6 , $connectionid);

Default Value

The $connectionid parameter specifies the index of the item in the array. The size of the array is controlled by the ConnectionCount property.

This property is read-only and not available at design time.

Data Type

Integer

EOL Property (IPWorksSSL_SSLServer Class)

The EOL property is used to define boundaries in the input stream using the value of the property.

Object Oriented Interface

public function getEOL($connectionid);
public function setEOL($connectionid, $value);

Procedural Interface

ipworksssl_sslserver_get($res, 7 , $connectionid);
ipworksssl_sslserver_set($res, 7, $value , $connectionid);

Default Value

''

Remarks

The EOL property is used to define boundaries in the input stream using the value of the property.

The EOL property is especially useful with ASCII files. By setting it to CRLF ("\r\n") , the incoming ASCII text stream can be split into lines. In this case, one event is fired for each line received (as well as in packet boundaries). The CRLF ("\r\n") . bytes are discarded.

The EOL property is a binary string. This means that it can be more than one byte long, and it can contain NULL bytes.

When reading the value of the property, if ConnectionId does not belong to a valid connection, then NULL will be returned, and the LastError property will contain a corresponding error message. If no error is encountered, then LastError will contain NULL.

The $connectionid parameter specifies the index of the item in the array. The size of the array is controlled by the ConnectionCount property.

This property is not available at design time.

Data Type

Binary String

IdleTimeout Property (IPWorksSSL_SSLServer Class)

This property contains the idle timeout for this connection.

Object Oriented Interface

public function getIdleTimeout($connectionid);
public function setIdleTimeout($connectionid, $value);

Procedural Interface

ipworksssl_sslserver_get($res, 8 , $connectionid);
ipworksssl_sslserver_set($res, 8, $value , $connectionid);

Default Value

0

Remarks

This property contains the idle timeout for this connection. This property is similar to DefaultIdleTimeout but may be set on a per-connection basis to override DefaultIdleTimeout. This property specifies the idle timeout (in seconds) for the connected client. When set to a positive value, the class will disconnect idle clients after the specified timeout.

This applies only to clients that have not sent to received data within the specified number of seconds.

If set to 0 (default), no idle timeout is applied.

Note: DoEvents must be called for the class to check existing connections.

The $connectionid parameter specifies the index of the item in the array. The size of the array is controlled by the ConnectionCount property.

This property is not available at design time.

Data Type

Integer

LocalAddress Property (IPWorksSSL_SSLServer Class)

This property shows the IP address of the interface through which the connection is passing.

Object Oriented Interface

public function getLocalAddress($connectionid);

Procedural Interface

ipworksssl_sslserver_get($res, 9 , $connectionid);

Default Value

''

Remarks

This property shows the IP address of the interface through which the connection is passing.

LocalAddress is important for multihomed hosts so that it can be used to find the particular network interface through which an individual connection is going.

The $connectionid parameter specifies the index of the item in the array. The size of the array is controlled by the ConnectionCount property.

This property is read-only and not available at design time.

Data Type

String

This property indicates whether the class is ready to send data.

Object Oriented Interface

public function getReadyToSend($connectionid);

Procedural Interface

ipworksssl_sslserver_get($res, 11 , $connectionid);

Default Value

false

Remarks

This property indicates whether the class is ready to send data.

This is true after a client connects but will become false after a failed call to Send or SendBytes. After a failed call to Send or SendBytes, the ReadyToSend event will fire and this property will be true when data can be sent again.

The $connectionid parameter specifies the index of the item in the array. The size of the array is controlled by the ConnectionCount property.

This property is read-only and not available at design time.

Data Type

Boolean

RecordLength Property (IPWorksSSL_SSLServer Class)

This property holds the current record length set by ChangeRecordLength .

Object Oriented Interface

public function getRecordLength($connectionid);

Procedural Interface

ipworksssl_sslserver_get($res, 12 , $connectionid);

Default Value

0

Remarks

This property holds the current record length set by ChangeRecordLength. When this value is a positive number, the class will accumulate data until RecordLength is reached and only then will fire the DataIn event with the data of length RecordLength. This allows data to be received as records of known length. This value can be changed at any time by calling ChangeRecordLength, including within the DataIn event.

A value of 0 (default) means this setting is not used.

The $connectionid parameter specifies the index of the item in the array. The size of the array is controlled by the ConnectionCount property.

This property is read-only and not available at design time.

Data Type

Integer

RemoteHost Property (IPWorksSSL_SSLServer Class)

This property shows the IP address of the remote host through which the connection is coming.

Object Oriented Interface

public function getRemoteHost($connectionid);

Procedural Interface

ipworksssl_sslserver_get($res, 13 , $connectionid);

Default Value

''

Remarks

This property shows the IP address of the remote host through which the connection is coming.

The connection must be valid or an error will be fired.

If the class is configured to use a SOCKS firewall, the value assigned to this property may be preceded with an "*". If this is the case, the host name is passed to the firewall unresolved and the firewall performs the DNS resolution.

The $connectionid parameter specifies the index of the item in the array. The size of the array is controlled by the ConnectionCount property.

This property is read-only and not available at design time.

Data Type

String

RemotePort Property (IPWorksSSL_SSLServer Class)

This property shows the Transmission Control Protocol (TCP) port on the remote host through which the connection is coming.

Object Oriented Interface

public function getRemotePort($connectionid);

Procedural Interface

ipworksssl_sslserver_get($res, 14 , $connectionid);

Default Value

0

Remarks

This property shows the Transmission Control Protocol (TCP) port on the remote host through which the connection is coming.

The connection must be valid or an error will be fired.

The $connectionid parameter specifies the index of the item in the array. The size of the array is controlled by the ConnectionCount property.

This property is read-only and not available at design time.

Data Type

Integer

SingleLineMode Property (IPWorksSSL_SSLServer Class)

This property shows the special mode for line-oriented protocols.

Object Oriented Interface

public function getSingleLineMode($connectionid);
public function setSingleLineMode($connectionid, $value);

Procedural Interface

ipworksssl_sslserver_get($res, 15 , $connectionid);
ipworksssl_sslserver_set($res, 15, $value , $connectionid);

Default Value

false

Remarks

This property shows the special mode for line-oriented protocols. When SingleLineMode is True, the class treats the incoming data stream as lines separated by carriage return (CR), line feed (LF), or CRLF. The EOL property is ignored.

The $connectionid parameter specifies the index of the item in the array. The size of the array is controlled by the ConnectionCount property.

This property is not available at design time.

Data Type

Boolean

Timeout Property (IPWorksSSL_SSLServer Class)

This property specifies a timeout for the class.

Object Oriented Interface

public function getTimeout($connectionid);
public function setTimeout($connectionid, $value);

Procedural Interface

ipworksssl_sslserver_get($res, 16 , $connectionid);
ipworksssl_sslserver_set($res, 16, $value , $connectionid);

Default Value

0

Remarks

This property specifies a timeout for the class.

If the Timeout property is set to 0, all operations return immediately, potentially failing with a WOULDBLOCK error if data cannot be sent immediately.

If Timeout is set to a positive value, data is sent in a blocking manner and the class will wait for the operation to complete before returning control. The class will handle any potential WOULDBLOCK errors internally and automatically retry the operation for a maximum of Timeout seconds.

The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive.

If Timeout expires, and the operation is not yet complete, the class fails with an error.

Note: By default, all timeouts are inactivity timeouts, that is, the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the Timeout property is 0 (asynchronous operation).

The $connectionid parameter specifies the index of the item in the array. The size of the array is controlled by the ConnectionCount property.

This property is not available at design time.

Data Type

Integer

UserData Property (IPWorksSSL_SSLServer Class)

The UserData property holds connection-specific user-specified data.

Object Oriented Interface

public function getUserData($connectionid);
public function setUserData($connectionid, $value);

Procedural Interface

ipworksssl_sslserver_get($res, 17 , $connectionid);
ipworksssl_sslserver_set($res, 17, $value , $connectionid);

Default Value

''

Remarks

The UserData property holds connection-specific user-specified data.

User-specified data may be set or retrieved at any point while the connection is valid. This provides a simple way to associate arbitrary data with a specific connection.

The $connectionid parameter specifies the index of the item in the array. The size of the array is controlled by the ConnectionCount property.

This property is not available at design time.

Data Type

Binary String

DefaultEOL Property (IPWorksSSL_SSLServer Class)

This property includes a default end-of-line (EOL) value to be used by incoming connections.

Object Oriented Interface

public function getDefaultEOL();
public function setDefaultEOL($value);

Procedural Interface

ipworksssl_sslserver_get($res, 18 );
ipworksssl_sslserver_set($res, 18, $value );

Default Value

''

Remarks

This property contains a default end-of-line (EOL) value to be used by incoming connections. Once the class accepts and establishes an inbound connection, it will set that connection's EOL to the value in this property. By default, this value is empty (""), meaning that data will be fired as it is received.

Data Type

Binary String

DefaultIdleTimeout Property (IPWorksSSL_SSLServer Class)

This property includes the default idle timeout for inactive clients.

Object Oriented Interface

public function getDefaultIdleTimeout();
public function setDefaultIdleTimeout($value);

Procedural Interface

ipworksssl_sslserver_get($res, 19 );
ipworksssl_sslserver_set($res, 19, $value );

Default Value

0

Remarks

This property specifies the idle timeout (in seconds) for clients. When set to a positive value, the class will disconnect idle clients after the specified timeout.

This applies only to clients that have not sent or received data within DefaultIdleTimeout seconds.

If set to 0 (default), no idle timeout is applied.

Note: DoEvents must be called for the class to check existing connections.

Data Type

Integer

DefaultMaxLineLength Property (IPWorksSSL_SSLServer Class)

The property includes the default maximum line length value for inbound connections.

Object Oriented Interface

public function getDefaultMaxLineLength();
public function setDefaultMaxLineLength($value);

Procedural Interface

ipworksssl_sslserver_get($res, 20 );
ipworksssl_sslserver_set($res, 20, $value );

Default Value

2048

Remarks

This property controls the default size of an internal buffer that holds received data while waiting for an end-of-line (EOL) string.

The minimum value for this property is 256 bytes. The default value is 2048 bytes.

Data Type

Integer

DefaultSingleLineMode Property (IPWorksSSL_SSLServer Class)

This property tells the class whether or not to treat new connections as line oriented.

Object Oriented Interface

public function getDefaultSingleLineMode();
public function setDefaultSingleLineMode($value);

Procedural Interface

ipworksssl_sslserver_get($res, 21 );
ipworksssl_sslserver_set($res, 21, $value );

Default Value

false

Remarks

This property instructs the component whether or not to treat newly established connections as line-oriented protocols. If this value is True, newly accepted connections will read the incoming data stream as lines separated by a carriage return line feed (CRLF), carriage return (CR), or line feed (LF) and will ignore the end of lines (EOLs).

Data Type

Boolean

DefaultTimeout Property (IPWorksSSL_SSLServer Class)

This property includes an initial timeout value to be used by incoming connections.

Object Oriented Interface

public function getDefaultTimeout();
public function setDefaultTimeout($value);

Procedural Interface

ipworksssl_sslserver_get($res, 22 );
ipworksssl_sslserver_set($res, 22, $value );

Default Value

0

Remarks

This property is used by the class to set the operational timeout value of all inbound connections once they are established.

By default, the timeout is 0, meaning that all inbound connections will behave asynchronously.

Data Type

Integer

KeepAlive Property (IPWorksSSL_SSLServer Class)

When True, KEEPALIVE packets are enabled (for long connections).

Object Oriented Interface

public function getKeepAlive();
public function setKeepAlive($value);

Procedural Interface

ipworksssl_sslserver_get($res, 23 );
ipworksssl_sslserver_set($res, 23, $value );

Default Value

false

Remarks

This property enables the SO_KEEPALIVE option on the incoming connections. This option prevents long connections from timing out in case of inactivity.

Note: System Transmission Control Protocol (TCP)/IP stack implementations are not required to support SO_KEEPALIVE.

This property is shared among incoming connections. When the property is set, the corresponding value is set for incoming connections as they are accepted. Existing connections are not modified.

Data Type

Boolean

Linger Property (IPWorksSSL_SSLServer Class)

When set to True, connections are terminated gracefully.

Object Oriented Interface

public function getLinger();
public function setLinger($value);

Procedural Interface

ipworksssl_sslserver_get($res, 24 );
ipworksssl_sslserver_set($res, 24, $value );

Default Value

true

Remarks

This property controls how a connection is closed. The default is True. In this case, the connection is closed only after all the data are sent. Setting it to False forces an abrupt (hard) disconnection. Any data that were in the sending queue may be lost.

The default behavior (which is also the default mode for stream sockets) might result in an indefinite delay in closing the connection. Although the class returns control immediately, the system might indefinitely hold system resources until all pending data are sent (even after your application closes). This means that valuable system resources might be wasted.

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you have sent (e.g., by a client acknowledgment), then setting this property to False might be the appropriate course of action.

This property is shared among incoming connections. When the property is set, the corresponding value is set for incoming connections as they are accepted. Existing connections are not modified.

Data Type

Boolean

Listening Property (IPWorksSSL_SSLServer Class)

This property indicates whether the class is listening for incoming connections on LocalPort.

Object Oriented Interface

public function getListening();

Procedural Interface

ipworksssl_sslserver_get($res, 25 );

Default Value

false

Remarks

This property indicates whether the class is listening for connections on the port specified by the LocalPort property. Use the StartListening and StopListening methods to control whether the class is listening.

This property is read-only and not available at design time.

Data Type

Boolean

LocalHost Property (IPWorksSSL_SSLServer Class)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Object Oriented Interface

public function getLocalHost();
public function setLocalHost($value);

Procedural Interface

ipworksssl_sslserver_get($res, 26 );
ipworksssl_sslserver_set($res, 26, $value );

Default Value

''

Remarks

This property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.

If the class is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

Note: LocalHost is not persistent. You must always set it in code, and never in the property window.

Data Type

String

LocalPort Property (IPWorksSSL_SSLServer Class)

This property includes the Transmission Control Protocol (TCP) port in the local host where the class listens.

Object Oriented Interface

public function getLocalPort();
public function setLocalPort($value);

Procedural Interface

ipworksssl_sslserver_get($res, 27 );
ipworksssl_sslserver_set($res, 27, $value );

Default Value

0

Remarks

This property must be set before the class can start listening. If its value is 0, then the TCP/IP subsystem picks a port number at random. The port number can be found by checking the value of this property after the class is listening (i.e., after successfully assigning True to the Listening property).

The service port is not shared among servers so two classs cannot be listening on the same port at the same time.

Data Type

Integer

SSLAuthenticateClients Property (IPWorksSSL_SSLServer Class)

If set to True, the server asks the client(s) for a certificate.

Object Oriented Interface

public function getSSLAuthenticateClients();
public function setSSLAuthenticateClients($value);

Procedural Interface

ipworksssl_sslserver_get($res, 28 );
ipworksssl_sslserver_set($res, 28, $value );

Default Value

false

Remarks

This property is used in conjunction with the SSLClientAuthentication event. Please refer to the documentation of the SSLClientAuthentication event for details.

Data Type

Boolean

SSLCertEffectiveDate Property (IPWorksSSL_SSLServer Class)

The date on which this certificate becomes valid.

Object Oriented Interface

public function getSSLCertEffectiveDate();

Procedural Interface

ipworksssl_sslserver_get($res, 29 );

Default Value

''

Remarks

The date on which this certificate becomes valid. Before this date, it is not valid. The date is localized to the system's time zone. The following example illustrates the format of an encoded date:

23-Jan-2000 15:00:00.

This property is read-only.

Data Type

String

SSLCertExpirationDate Property (IPWorksSSL_SSLServer Class)

The date on which the certificate expires.

Object Oriented Interface

public function getSSLCertExpirationDate();

Procedural Interface

ipworksssl_sslserver_get($res, 30 );
