Hello Joachim,

Thanks for the response.

The CAS server doesn't send logout requests to gateway CAS clients, so there is 
no point of putting "phpCAS::handleLogoutRequests();".

The renewAuthentication() function will redirect you to CAS every time.  I'm 
wanting the gateway functionality, where if the user is authenticated already 
then phpCAS does the handshake and returns the user, but if not authenticated 
don't redirect to CAS login.

I'd like a way to do this gateway functionality every time the abc.com page is 
loaded (ie. Check authentication against the CAS server every time, but not 
force user to be authenticated).

Thanks,
Matt

Please have a look at the documentation [1] how to handle logout
requests. Using the gateway feature _does_ work with the logout request.
As far as i can tell from your code snippet you are missing the

phpCAS::handleLogoutRequests();

that would handle the incoming logout request.
Aside from that you can try using the phpCAS::renewAuthentication()
function that will reauthenticate your phpcas session with a new ticket
from the cas server.
The function phpCAS::setCacheTimesForAuthRecheck(0) you are using only
"works" for non authenticated users. It's used to set how often a
gatewayed page will recheck for an existing CAS session for an anonymous
user.

Best Regards,

Joachim
