WCCP has been mentioned quite a bit, and as I understand it, it is a Cisco thing which can work with any WCCP compliant software eg Squid, or a dedicated appliance like Cisco Cache Engine. Since people are asking about WCCP in a Squid forum, I assume they are using Squid. Does that mean the Cisco appliance is not as good as Squid? In particular, my question is how well does the appliance handle Youtube, or dynamic URL caching, in general? Anyone like to comment?
