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.
