WCCP

Post by Saeeds »

Hello,
We have a sun LX 50 machine ( sun Linux ) which we r using as a cache/proxy server and squid 2.5s3 is running on it.We have applied policy based routing on our Cisco 7206 router and all the browsing request are transparently served by the LX50 machine, my question is that how could we use WCCP over squid machine and what are the advantages of using WCCP ,is it suited for our current senario as the browsing is already transparent to the clients browser,and why should we enable WCCP on router sa interception is already being done by using "policy based routing". Waiting for your prompt reply, thanx in advance.

Regards,
Saeed Ahmed.

Dear
Salam,

Squid Cache Transparency and WCCP
Version 1.1: 12 September 2001


Introduction
In the absence of a Layer-4 switch (eg. Foundry, Alteon) Squid transparency is probably best achieved using Cisco's Web Cache Coordination Protocol (WCCP). Policy Based Routing (PBR) can be used but suffers from one significant limitation: failover. If you choose to use PBR and your Squid cache dies or needs to be rebooted then all your web surfing stops. Further, WCCP allows multiple caches to participate (for further fault tolerance) while PBR only allows one. Squid only supports WCCPv1 at this time. WCCP does place a load on your router in excess of normal HTTP traffic. Hence, ensure that your router has adequate RAM and CPU horsepower.

For more information check out Squid Cache Transparency and WCCP
