We are using Oracle 9i R2.xx PL/SQL function to call a VB .Net (version 1.1) web service residing on an IIS server, using utl_http. The web service appears to be executing, but we can not get the return value from the Web Service. When we do the get_response we get a Response of 100, and Reason of "Continue". After reading some documentation it seems Oracle 9i can not process a 100 Continue message. I have tried to change the protocol to HTTP/1.0 instead of HTTP/1.1, but that causes us to get a 404 - Object Not Found error. I have tried to find a way to set the protocol in the web service, but have been unsuccessful.

Has anyone had any success with this or can anyone offer any suggestions?
