I can see how to use the XML-RPC specs to generate server-challenge strings for authentication, etc. But what I don't know is how to use that (the user's username, passwd, or anyt authentication that can be gotten from XML-RPC) to actually have PHP authenticate the user (and grab their protected RSS feeds.)
Does anyone have any tips on how to do this (any aspects of libcurl that I'm missing?) I have tried http://username:email@example.com/data/rss?auth=digest, and I have tried that using the md5 hash of my password - but clearly I'm missing something.
If you could point me in the right direction, that would be appreciated.
(edit: changed example URL for digest RSS feeds)
