[squid-users] Serious probem with transparent caching?

Hi,

I've been running a transparent cache using WCCP for a few weeks now. On
several occasions I have encountered problems with web site updates not
showing up for users. Hitting refresh in the browser doesn't work.

I understand why this is happening, but I dont' know of a good fix. So
far, the best i can do is exclude the website in question from the
cache. This is not a very practical solution. I simply cannot keep
going in and adding server IP addresses to the cisco access-list every
time a user complains.

If I have the cache server query the origin server for modification
information for every cache request, there will be little advantage to
caching. At this point, I am considering turning off the cache.

How have other cache admins dealt with this issue?
