Feature Request - pass operation from binding to transport #1497

Property Drilling - operation

The API I'm working with (eBay Trading API) needs the operation being performed at the transport level in an HTTP header for the raw XML version, or the query string in the SOAP version. I am unable to use this library on the API

• Sample XML API that requires this (X-EBAY-API-CALL-NAME)
• Sample SOAP API that requires this (callname parameter)
