Re: Cache Flow & wccp v2.0

I ould guess not. But we hav a cisco person lurking on the list so I am
sure he will respond :)

My guess is they purchased the rights to use wccp or reverse engineered
it. Most likely the former rather than the latter.

I can tell you from my experience. My stack of Cisco Cache Engines (550's)
out performs my 3 Cacheflow boxen with transparent proxy. The cacheflows
have their place but price/performance is still too high. I replaced the
9Gig drives shipped by Cisco with 18Gig drives and have external storage
on my boxes and they work absolute flawless. Of course I still use squid
to get my Sky Cache feed.
