CAS-infinite-redirect-loop
Within the last two weeks I started experiencing the same problem on our CAS
deployment. Our Environment is as follows:
Two instances of tomcat running on two different boxes(Clustered for Session
Replication)
Each CAS is configured to use the Jboss TreeCache
Both CAS boxes sit behind a BigIP load balancer.
This configuration has been running rock solid, successfully adding and
removing tickets from the TreeCache for the past year but something changed
within the last week and now I can not run two servers in the pool. I have
checked the deployed applications, no new versions have been pushed to
production within the last 6 months.
Log from the CAS Server that initially processed the request:
2010-12-08 14:37:04,611 DEBUG

On the redirect..the request hits the other service and here is the log:
2010-12-08 14:37:04,654 DEBUG

[org.jasig.cas.CentralAuthenticationServiceImpl] - <ServiceTicket

Ath this point I am just looking for suggestions as to where to look to
figure out what is going on. Any help is greatly appreciated.
