What value to use for serverName?- Infinite loop during redirection problem

[Scott Battaglia]

If you're using the Yale Java Client you could modify the client to look it
up in JNDI vs. the web.xml.  If you're using the JA-SIG CAS Client for Java
you could also look it up in JNDI (its a configuration change).  You could
then define the server name in a context file outside of the war file.  I'm
not sure if that would help in your situation.

The server name needs to be hard-coded. Otherwise, it would need to get it
from the HTTP request which is constructed by the client and not necessarily
correct.
