Yes there is a 3.0 package shipping with SuSE. Is there an easy way to
determine what policies were built into the 3.0 package from SuSE? I am
not sure what heap is, but if needed I will fix this before going live
with the production server!!! Will this cause the server to not work
properely? or is it just a security/performance issue?

So for defaultsite I would need something like
defaultsite=owaserver.com/exchange vs. owaserver/exchange? and these
entries added to the hosts file on the squid server since this points to
the internal exchange server?? Also, these names should be different
than the FQDN that hits the squid box? correct?

vhost?? is this /etc/hosts? I haven't seen any reference in my research
thus far on vhost, but I may just be to much of a novice I suppose. The
only thing I see similar is the visible_hostname directive.

So would I just add the option "originserver" like this??

cache_peer owaserver parent 80 0 proxy-only originserver front-end-https=on login=pass

I had a hard time finding what this did exactly and the sample config I was sent kept complaining about it.

Thank again for your time Henrik!!
