-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Mani,
- From what you described, it doesn't sound like you have the option to set additional http headers. I remember running in to that with one of the perl XMLRPC libraries. It didn't really expose a way to set additional http headers; so, I think I had to make a new class that inherited the provided one with some modified functions allowing the additional headers to be set. The problem here is that I couldn't find any way of doing authentication with XMLRPC other than basic auth, which wasn't an option in our (NCSU) environment. So, I added the requirement of using additional http headers that provide the necessary authentication bits. Unfortunately, not all XMLRPC libraries expose a way to set additional http headers. If anyone knows of another way of doing XMLRPC authentication, please let me know.
