[squid-users] can SQUID co-exist with Microsoft ISA in a cache hierarchy?

Hello everyone.

Could anybody tell if SQUID can co-exist with Micosoft ISA in a cache
hierarchy. I have the situation whereby ISA sits (and caches!) in front of
some web servers in a data centre and local caches are required in some 100+
distributed offices. Do I have to deploy ISA in the distributed offices or
do I have a choice ?! If they can co-exist how does it work ? if not,
please could you explain why ?

Thanks in advance.
