CAS with phpCAS and mod_proxy

[Andrew Stutzman]

Does anyone have experience using CAS and mod_proxy?

I'm currently integrating CAS into a PHP application on a server that  
uses mod_proxy to proxy to the correct web server for the  
application.  Even when I use the setFixedServiceURL() method either  
CAS or mod_proxy keep bypassing the proxy of the webserver and I keep  
getting sent to the wrong url.

For example.. let's say my base url for the application is https://myserver.tcnj.edu/appname/index.php 
.  This is the url I give CAS as the service.  The CAS login page even  
shows this as the service name in the url when you get to the login  
page.  However once I login I keep getting sent to:  http://myserver.tcnj.edu:8005/index.php 
.  Even using setFixedServiceURL() doesn't help.  I've used the  
setFixedServiceURL() to send the app to a completely separate website  
and that works just fine.

Any suggestions?
