Re: [squid-users] sorry, i updated my email mode, and i have a question about wccp

Hello Dear Eliezer:

Thanks , i build squid2.7stable9 at ubuntu

and i prepare to realize wccp at "http_port 3128 transparent"( but this
is interception mode only ) at firep step.

second step is wccp at " http_port 3128 transparent tproxy " ( it will
is transparent mode ) .

although i search more info for realizing wccp interception mode , but i
don't find good way until now .

But thanks for your advisement again.

John
