[users@httpd] Reverse Proxy with Apache. CAS + two tomcat servers.

[Jorge Infante Osorio <jo...@uci.cu>]

Hi all.

I have an issue in reverse proxy with apache, tomcat and SSO using CAS. 

The problem is that my reverse proxy work just fine when I use an Apache Server as the reverse proxy with two back-end tomcats. 

But when the I include SSO with CAS to authenticate the user with access to the tomcat servers the internal redirections are missing to the users that use the reverse proxy and I don´t know why. 

The CAS cookie are not pass between the cassified servers.

Can anyone have any idea on this or implement a scenario like this?

My proxy configuration:
**************************************
LoadModule proxy_module      /usr/lib/apache2/modules/mod_proxy.so
LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so
