The path to the website hosting the GISB adapter.
This is the virtual path of the application that will host the instance of the GISB adapter. It is not necessary to include the schema ("http") or host information: the adapter will ignore everything other than the path information. For example, if the URL you would post to is "http://localhost/GISBReceiver/GISBServer.aspx", you only need to set "/GISBReceiver/GISBServer.aspx".
This property is not available in the Sender.
