[Mailman-Users] Why https only works from remote hosts ?

[Oliver Egginger]

Hello,

from remote hosts everything works fine.

I'am using mailman 2.0.6 (with Apache 1.3.20 and OpenSSL 0.9.6b in the back).
List subsciption (and so on) works very well (remote and local),
but when I visit the list-owner admin page (via https) from my local machine 
( https://<my_host>/mailman/admin/test ),
I receive this error message by trying to send the passwort:
--------------------------------------------------------------
Bad Request Your browser sent a request that this server could not understand.

Reason: You're speaking plain HTTP to an SSL-enabled server port.
Instead use the HTTPS scheme to access this URL, please.
--------------------------------------------------------------
The causer is the obversely Post Action in the (generated) adminpage-URL:
ACTION="http://<my_host>:443/mailman/admin/test">
(This throws away the https://<...> suffix.)	:-(

So I thought (at first) it would get into general trouble,
but when I doing the same from a remote host everything works fine, cause the post action looks 
(in this case) like this:
ACTION="/mailman/admin/test">
(This preserves the https://<...> suffix.)	:-)

Why mailman works in this manner ?
Do I something really stupid ?
I can't see my fault, so if you could give me a  clue, I would be very greatful.


regards
Oliver
