Re: [squid-users] defaultsite=domainname?

Amos,
Here's a challenge, I can't find the reason why the Header rewrite is
not happening? My configuration has only 1 "web
server"(unified1.abstract.net, IP:192.168.0.10) behind the reverse
proxy server(proxy1.abstract.net, IP: 192.168.0.20)

What I want the reverse proxy server to do is:
a) not cache anything, essentially just stream the web server content
straight to the client
b) *suppose* the Header needs to be rewritten, but I am assuming this
get's done by virtue of using the following lines in squid.conf:

###
cache_peer unified1.abstract.net parent 80 0 no-query originserver
forceddomain=unified1.abstract.net name=myAccel

###
acl FMS dstdomain unified1.abstract.net
http_access allow FMS
cache_peer_access myAccel allow FMS

------------------ Any ideas??????? Below is some logging
---------------------- THNKs

The request GET http://proxy1:80/configMultiSiteConfigRequest is
ALLOWED, because it matched 'PROXY1'
