We're having a problem with an external webmail site that uses round robin dns: > webmail.domain.com Server: 10.51.#.# Address: 10.51.#.##53 Non-authoritative answer: Name: webmail.domain.com Address: 12.145.#.5 Name: webmail.domain.com Address: 166.73.#.139 Name: webmail.domain.com Address: 12.145.#.56 Bringing up the original webmail site works fine, but a user's session gets bounced between The different webmail servers during authentication.

Is it a problem with the webmail site not maintaining a session between the proxy server and the mail server? Is there a way to have the Squid proxy use a consistent IP address for a URL instad of a new DNS lookup? We're running squid-3.0.STABLE6. Thanks, Mark Krawec mark@xxxxxxxxxx
