/* http_client allows you to talk (asynchronously, again) to HTTP servers.
In the "background" it will send the whole query and wait for a complete
response to come back. Right now it's only used by the MSN Passport
authentication code, but it might be useful for other things too (for
example the AIM usericon patch uses this so icons can be stored on
webservers instead of the local filesystem).
Didn't test this too much, but it seems to work well. Just don't look
at the code that handles HTTP 30x redirects. ;-) The function is
probably not very useful for downloading lots of data since it keeps
everything in a memory buffer until the download is completed (and
can't pass any data or whatever before then). It's very useful for
doing quick requests without blocking the whole program, though. */
