[users@httpd] mod_load_balance issue

[Günther Mittermayer]

Hi all,

i have httpd working with mod_proxy and mod_load_balance, but my system is very unstable. In the middle of my session I get some 500 Internal Server Error messages.  If I comment out from my httpd.conf all application servers but one, the problem goes away.

It seems to me that apache is not forwarding the requests to the same server within the same session.
As far as I understand, this is what the "stickysession" parameter should do...

Below is the part of my httpd.conf that matters, am I missing something?

Thanks in advance,
Günther.
