Dear, I've implemented a Squid reverse proxy that works OK. I have several HTTP and HTTPS sites setup in reverse mode, but now one of them has to change the hostname from server.company.com to mail.company.com. If I define an alias in our internal DNS as follow: mail.company.com CNAME server.company.com or add a new A record pointing to the same IP as server.company.com: mail.company.com A x.x.x.x Will reverse Squid work OK without any changes ??? Or do I have to have mail.company.com mandatory in the ACL dstdomain clause ??? Thanks a lot, regards. Roberto
