HTTPVersion Property

The HTTP Version used by the class.

Syntax

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

Default Value

"1.1"

Remarks

This property specifies the HTTP version used by the class. 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 class 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 class will use the internal security implementation in all cases when connecting.

This property is not available at design time.
