Reverse proxy with apache


Hello my fellow linuxers,

I'm having a problem with reverse proxy on apache.

In the proxy I have a config like this:

<VirtualHost xxx.xxx.xxx.xxx:80>
RewriteEngine on
ServerName test2.mydomain.se
PROXYRequests Off
ProxyPass / http://app.otherdomain.se/
ProxyPassReverse / http://app.otherdomain.se
SecRuleEngine On
SecAuditEngine On
</VirtualHost>

When I try to reach the "http://test2.mydomain.se/Web_Framework/startpage.login?user=testuser&pwd=testpassword"
I get an error on a script in firebug.

GET http://test2.mydomain.se/Web_Framewo...?tagname=bulls

500 Internal Server Error
62ms
startp...tpassword (row 68)
document.getElementById(id) is null
[Stop by error] document.getElementById(id).innerHTML = result;

It seems to me that there is a problem with some XML stuff or something but I'm not sure about that.

Anyone got an idea?

Best regards

Johan

well you need to look at the server side logs of whatever is reporting this error. only posting client side error messages isn't going to shed much light really.

I've also tested another proxy server (apache trafficserver) but that didn't help either.
The proxy server doesn't record anything in the logs about the problem.

ok well that doesn't look relevant at all. If you think it is then google the error message there.
