Re: [squid-users] 2.6S1 WCCP2 problems

Tino,

Thanks for your config, i added the vhost and vport=80 options to my
config, but i am still having the same problems. As for lo0 on the
router, i have never had to setup this up in the past but i tried it
anyway and it made no difference. When i have talked to the Cisco guys
before they stated that WCCP simply needs an IP and will grab any
configured IP on the router, it doesn't matter. I think i am going to
submit a bug, i don't know why squid is sending back a bad id.

Thanks,
 Bryan
