I want to config my transparent squid to use an external proxy (with user/password) authentication when accessing a specific set of sites. At present the situation is as follows: When I want to access a specific site, say www.example.com, I am required to set my browser proxy settings to use an external proxy, for instance proxy.external.com port 8080, and then I am required to enter a user and password. Basically the site www.example.com is only accessible through this proxy which is external to our site. On our site we have our own squid box configured as transparent cache (using WCCPv2), so what I would like is to be able to access www.example.com (transparently), i.e. without having to change my browser proxy settings. Can anybody help me with the squid config?
