You can not do that, every ticket will be used only once - and mod_auth_cas
with parse the ticket and consume it. If you already have cassified
application then you should not protect that application behind mod_auth_cas
again.

You can surely add reverse proxy infront of CAS application - but that can
not use mod_auth_cas, So I use single apache httpd with multiple virtual
hosts - and application which need two levels fo protection I just put them
basic authentication.
