Transparent Proxy Issue

[Lim Boon Siong]

I have a squid proxy server setup in my network. I was using TopLayer to redirect the port80 HTTP signal to proxy as a transparent.
But the problem now is when I put on the proxy server the user cannot go to some web-site, and after putting off it was fine, please tell me why it was happen like that.

Hi,

did you modify the squid acl?

Are you seeing something in the squid logs.

Some site are working and some are not... this is the weird part of your problem.

Thanks,
JP

My scenario is, I have 4 Squid Proxy server on the network, and each other was set as sbiling mode to each other. we have no problem during previous time and has been using for almost one years, but now it getting this problem.
I try to purge all the cache in the /cache dir and start all over again , but the problem was still proceed.
