HTTPVersion Property

The HTTP Version used by the component.

Syntax

public String getHTTPVersion();
public void setHTTPVersion(String HTTPVersion);

Remarks

This property specifies the HTTP version used by the component. Possible values are:

• "1.0"
• "1.1" (default)
• "2.0"

When using HTTP/2 ("2.0") additional restrictions apply. Please see notes below for details.

HTTP/2 Notes

When using HTTP/2 only secure (TLS/SSL) connections are currently supported. Attempting to use a plaintext URL with HTTP/2 will result in an error.

If the server does not support HTTP/2 the component will automatically use HTTP/1.1 instead. This is done in order to provide compatibility without the need for any additional settings. To see which version was used check NegotiatedHTTPVersion after calling a method. The AllowHTTPFallback setting controls whether this behavior is allowed (default) or disallowed.

HTTP/2 is supported on all platforms. The component will use the internal security implementation in all cases when connecting.

This property is not available at design time.

Default Value

"1.1"
