Yes. I was prepared that this might not cover all aspects of what people
would want...

All URLs specified on the same command line will use the same "handle" and
thus the SSL Session ID Caching should take place and work. A session ID is
used in the SSL handshake, so using the cache is only in effect when a
previous SSL connection to the same site was disconnected. Thus, as long as
connections are persistant and re-used, there will be no re-using of session
IDs.

It *might* be possible. It all depends on what kind of interfaces OpenSSL
offers to fiddle with these things. I haven't yet discovered any such ones. A
session for OpenSSL is a struct that I just can't print out. Or more
accurately, I can print it, but I can get it back again in any sensible way
AFAIK. If there's an OpenSSL hacker reading this with other info, please
prove me wrong!

If I were you, I would seriously consider using the perl/python/tcl/whatever
libcurl interface instead, as that would give you a much simpler (at least
quicker) way to get to the cached Session ID heaven.

I hope so. It all of course comes down to what kind of functionality you're
after, and what we'll agree on that (lib)curl should offer... Currently (in
the 7.9 pre-releases and the CVS development sources), the -c option simply
dumps all internally known cookies to a specified file.

BTW, while I'm writing, the 7.9 pre-release 3 was uploaded earlier today.
Newer and better. -R and libtool 1.4.1 are noteworthy news in there.
