[support] Unable to keep logged in to some sites when behind a proxy

[Francesco]

Hi everybody, sorry if I'm submitting this twice but the first time I
wasn't subscribed to the list yet, and since my message didn't show up
on the archives, maybe nobody received it actually.

Please let me know if someone has already experienced such problems,
eventually giving me some pointer about the solution - assuming there
is any (I'm forwarding my message here below, please have a read).

By the way, I tried searching the previous postings with the link
http://lists.drupal.org/drupal-support/swish.cgi?idxname=drupal-support
as reported on
http://lists.drupal.org/listinfo/support
but I got a 404 response.

Thanks for your patience, I'm quoting my message here below.
Have fun,
Francesco

Hi everybody,
my name is Francesco, I'm new here so first of all let me thank you
very much for your dedication - to all the creators, developers and
community - Drupal is fantastic and the online resources are
invaluable.

I've been using Drupal for some time now, both locally and installing
it on some websites, and everything has gone fine so far.

But now I'm experiencing some problems logging in to some sites, one
of which is drupal.org.

The creation of the new account completed successfully, but when I try
to log in, it simply pulls me out without giving me any warning. If I
try to login with wrong credentials then I receive a "wrong
usename/password" error.

Some details:

- I connect to the Internet with an ISP that forces me behind a proxy,
limiting me to use http/https on port nr. 80.

- I've published two Drupal 6.10 installations on different hosts, and
I happen to experience such problems only on one of them:
frasic.altervista.org - works perfectly
toscana-offerte.com/drupal - accepts the login but keeps me logged
out, just like drupal.org

- I am able to log into the websites with another connection (one that
doesn't force me behind a proxy). Once I'm logged in, I can disconnect
(keeping the browser open), connect again with the proxy connection
and continue surfing without being thrown out.

The thing that hassles me is that on frasic.altervista.org I'm
experiencing no problems at all.
I have no clue, any suggestion or pointer will be really welcome.

I hope this was the right place to ask for help about this issue. I'd
have some more questions I'd like to submit to the community, and my
idea was to post them on the drupal.org forum, but as you know by now,
I cannot easily use it.

Just to let you know, to get around this connection problem with the
trick mentioned above (login - change connection - continue surfing)
I'd have to subscribe another Internet connection but I currently can
not afford it (the experiment was made with a friend's connection).

Please let me know if I can submit those issues here in the mailing
list - that's no bug report or feature request, it's about making some
context-aware sidebar boxes (unfortunately I wasn't able to find a
solution in the existing threads, although there are many which cover
the "context-aware sidebar content" and "pass variables to box
content" topics)

Thank you very much for your attention, feel free to ask in case you
are interested in this issue and need further details to investigate
it.

Wish you all the best,
have fun,
Francesco
