cassification of a web page that is also accessible behind a reverse proxy

[Mikael Kermorgant]

Hello,

I have a web page that is either :
- accessed directly for internal users of the enterprise
- accessed via a reverse proxy on our DMZ for external users

I've tried to set up mod_cas on the apache server serving the web
page. It works inside, not for external users. External users get
redirected to the CAS server for logon. It logon is ok, they get
redirected to internal address, which is unaccessible from the
outside...

Here's what I have on the reverse proxy :
ProxyPass / http://internal_address/

Is there anything I can configure to get a working setup ?

Thanks in advance,
