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? -matthew
