Hi,
I have two Squid boxes behind an LVS (Linux Virtual Server) server. The
two boxes are forward proxies for two Apache webservers on the same
private network.

Squid1 accelerates Apache1
Squid2 accelerates Apache2
Both squid boxes are set up as parents of each other , but with
"prefer_direct on".
My thinking is that if one of the back-end Apache's goes down then the
Squid that was accelerating that box will go to it's parent (accessing
the alternate Apache.)
I am hoping that by using "prefer_direct on" I will be able to avoid
forward loops. I am presuming that HTTP errors (such as 404's) from the
Web servers won't cause such looping.
Am I right?
TIA,
John
