Morino, I'm entirely certain what you're trying to do, but it is
definitely possible to have AOLserver log in as a client to another
web-based system using cookies and everything (and with some extra
effor, it even works for SSL). I know because I've done so in the
past (back in 2003).
However, you're going to have to write code to do it, AFAIK there is
nothing stock in OpenACS for that. Ah, the client-side cookie
handling you need is in
Between AOLserver, nsopenssl, OpenACS, and tclwebtest, you have all
the pieces you need. However, while not terribly difficult, the
programming to make it work is not at all trivial, either.
I probably should have contributed that remote web login code I wrote
to OpenACS, but after developing it I ended up not actually using it
in Production, so I quickly forgot about it. If anyone really wants
it I can send you the code (particularly if you will do the work to
better integrate it into OpenACS). It includes, for example, a proc
which remotely logs in to another OpenACS instance.
