[squid-users] WCCP and ICP

Okay, I have been fighting to get WCCP and ICP working in a two server test= cluster for weeks now with no luck.

The WCCP was not big deal but I think that with just WCCP you just get a ro= uter to send the HTTP requests to each server. I do not think that if the = server doesn't have the request the router checks the other server. What t= hat would mean is that with just WCCP and two servers we only get half as m= any potential HITS as we could if both servers were searched for each reque= st.

That being said here is my confgs from the two test servers. Like I said W= CCP works fine.

How do I get the two servers to talk to each other to improve cache hits on= the stream?
(I plan on putting this into a bigger group of servers.)

Thanks in advance.
Steve

Both compiled with:

CFLAGS="-DNUMTHREADS=128" ./configure --prefix=/usr --includedir=/usr/include --datadir=/usr/share --bindir=/usr/sbin --libexecdir=/usr/lib/squid --localstatedir=/var --sysconfdir=/etc/squid --enable-wccpv2 --enable-linux-netfilter --enable-default-err-language=English --enable-err-languages=English --enable-async-io --enable-removal-policies=lru,heap --disable-auth --disable-ident-lookups --enable-storeio="aufs" --enable-cache-digests --enable-icmp --with-maxfd=65536 --enable-poll
