Due to the fact that the ASA has a limitation with WCCP (http://www.cisco.com/en/US/docs/security/asa/asa80/configuration/guide/dhcp.html#wp1094628) of having the client and WCCP proxy on the same interface not allowing WCCP redirect pass through. I was curious if anyone has deployed a WSA in a dual homed infrastructure to support the multiple interfaces and pass through limitations? Would love to have p1 assigned the inside proxy and p2 assigned for the dmz proxy. I have not tested this yet but will be tomorrow, figured I would post tonight to solicit feedback.

Cisco ASA 5550 - 8.0.4(32)
outside - x.x.x.x
dmz - 10.255.0.100 /24
inside - 10.0.0.100 /24
WSA P1 - 10.0.0.200 - currently supports inside -> outside proxy
WSA P2 - 10.255.0.200 ????? to support the dmz -> outside proxy???
