[Typo3] Typo3 with HTTP-Proxy

[Holzhammer Wolfgang]

Hi all,

is it possible to run typo3 BE behind a http-proxy?

I 've installed typo3 in the web-root-subfolder "typo3" (BE-URL without 
proxy is http://cms-server/typo3/typo3/).
I 've configured the proxy successfully and it forwards all "/typo3" 
requests to the cms-server. ( http://proxy-server/typo3/)
So far this works fine.

When I want to use e.g. frontend-editing typo3 responses paths as they 
are real (http://cms-server/typo3/typo3/).
Obviously therefore the cookie doesn't fit (because it was issued for 
http://proxy-server) - so I got a session-timeout error.

The same problem I get when I use phpMyAdmin (all content is responded 
directly from cms-server).

any ideas - tia,
wolfgang
