I'm a bit of a newbie when it comes to web programming. When you say I should you the multipart encoding, do you simply mean that I should add the file content using the curl_formadd() function, or is there additional headers to add as well?

I tried that as well, but I get the same results.

I can easily get this with Visual Basic using the .NET objects such as HTTPWebRequest, however I need to develop this application in a native Visual C++ / MFC application. IF I can't get this to work, I might simply create a DLL using VB to use from C++ (not ideal, but it should work).

Do you know a tool or website that can show me what my application is sending to the server? Otherwise I'm trying to see if Tomcat can log those requests.
