I have a strange issue with Web Proxy. My Config is a Multiserver install on RHEL 6.2 64 bit. Have Web Proxy installed on a separate box. The issue is while I am able to login using web sometimes, at other times (seems quite random) it re-directs the requests directly to the mailbox server. And I am not getting a clue as to when this happens? Isn't the whole idea of proxy that the user doesn't directly connect to the mailbox server? I have been trying to look at the log files (/opt/zimbra/log/ nginx.log & nginx.access.log). No clue.
https://webmail.mydomain.com works fine some times (webmail.mydomain.com) being the web proxy host
and at other times the moment I login it immediately re-directs the url to
https://mailstore1.mydomain.com or https://mailstore2.mydomain.com
This is happening with all accounts, on different PCs. I even tried clearing the cache & other stuff in the browsers, restart the browser etc, still it happens. And at other times it logins perfectly.
Any clue is highly appreciated.
