Hi, i have this old asp.net 1.1 webservice which i need to extend to send an HttpWebRequest to a remote web app over https. The recieving web app and server is not under my control. i must be doing something stupid that i can't see but everytime my webservice calls GetRequestStream it failes with: exception: "The underlying connection was closed: Could not establish secure channel for SSL/TLS." inner: "Unable to read data from the transport connection." calling the same code from a console app works.. so it must be something that has to do with the security context under which the webservive is running. not sure waht i need to do.. can someone help please?
