WebUpload Control

Properties   Methods   Events   Config Settings   Errors  

The WebUpload Control is used to upload files to RFC 1867-compliant web servers.

Syntax

WebUpload

Remarks

The WebUpload Control supports both plaintext and 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.

To use the control as a file upload client, provide the file names (paths) in the FileVars properties and optional form variables in the FormVars properties.

Then, set the URL property to the address of the page or script that accepts the files and call the Upload method. Alternatively, you can call the UploadTo method with URL as a parameter.

The UploadProgress event is fired during upload, which shows the progress of the upload. The Transfer event shows the server response (normally an HTML page).

Accept Property (WebUpload Control)

This property includes a list of acceptable MIME types for the request.

Syntax

webuploadcontrol.Accept[=string]

Default Value

""

Remarks

If this property contains a nonempty string, an HTTP Accept header is added to the request.

The Accept header is used for content negotiation. It provides the server with a comma-separated list of MIME types that are acceptable for its response.

Data Type

String

Authorization Property (WebUpload Control)

This property includes the Authorization string to be sent to the server.

Syntax

webuploadcontrol.Authorization[=string]

Default Value

""

Remarks

If the Authorization property contains a nonempty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

A common use for this property is to specify OAuth authorization string.

This property is provided so that the HTTP control can be extended with other security schemes in addition to the authorization schemes already implemented by the control.

The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".

Data Type

String

AuthScheme Property (WebUpload Control)

This property specifies the authentication scheme to use when server authentication is required.

Syntax

webuploadcontrol.AuthScheme[=integer]

Possible Values

authBasic(0), 
authDigest(1), 
authProprietary(2), 
authNone(3), 
authNtlm(4), 
authNegotiate(5), 
authOAuth(6)

Default Value

0

Remarks

This property will tell the control which type of authorization to perform when the User and Password properties are set.

This property should be set to authNone (3) when no authentication is to be performed.

By default, this property is authBasic (0), and if the User and Password properties are set, the control will attempt HTTP Basic Authentication. If AuthScheme is set to authDigest (1), authNtlm (4), or authNegotiate (5), then Digest, NTLM, or Windows Negotiate (Kerberos) authentication will be attempted instead.

If AuthScheme is set to authProprietary (2), then the authorization token must be supplied through the Authorization property.

If AuthScheme is set to authOAuth (6), then the authorization string must be supplied through the Authorization property.

Note: If you set the Authorization property and AuthScheme is not authProprietary or authOAuth, then the AuthScheme will be set automatically to authProprietary (2) by the control.

For security, changing the value of this property will cause the control to clear the values of User, Password, and Authorization.

Remarks

This property determines what happens when the server issues a redirect. Normally, the control returns an error if the server responds with an "Object Moved" message. If this property is set to frAlways (1), the new URL for the object is retrieved automatically every time.

If this property is set to frSameScheme (2), the new URL is retrieved automatically only if the URLScheme is the same; otherwise, the control fails with an error.

Note: Following the HTTP specification, unless this property is set to frAlways (1), automatic redirects will be performed only for GET or HEAD requests. Other methods potentially could change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server or port are different from the existing one, User and Password are also reset to empty. If, however, this property is set to frAlways (1), the same credentials are used to connect to the new server.

A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g., new authentication parameters).

The default value is frNever (0). In this case, redirects are never followed, and the control fails with an error instead.
