Type Default Value Read Only Description
String "" No Additional HTTP headers to send in the request.




This property specifies HTTP headers added to the default headers. It must follow the syntax of HTTP headers.

For example, you may add the cookies from a response to a request under some authentication (e.g. ASP.NET Forms) where a session ID is returned for subsequent requests so re-authentication is not needed. See the NoCookie property for further information if you specify cookies in the HTTP headers.
