property URL: TServerRequestURL

 It is highly recommended that you only use relative URLs only in this property. Most modern web browsers will prevent server requests that don't access resources from the same origin (protocol, host, port number) from executing, unless the web server specifically allows such a request. Such a request is referred to as a cross-origin resource sharing request. For more information on how to permit such requests with the web server, please see the Configuring the Web Server topic.
