Hello Marvin,

when you say " we don't really support hot deploys of CAS on Tomcat", you
only talk about cas server right ?

Hot deploy an application with AuthenticationFilter (i mean cas client) is
not a problem ?

I switch from openAM to CAS due to hot deploy problem, so your answer is
important to me :)
