Update: I haven't changed anything yet but have noticed that it sometimes works. It's currently working perfectly but other times it stops working. I think it's got something to do with the login/authorization. I just logged in on 1 pc and it worked fine. I then went to another PC with a browser I never use (IE10) and entered invalid credentials to the nagios login prompt. This gave me access to the web console anyway! So once any user at all has logged in successfully, anybody who tries to access the page is already authenticated. Why would this be happening? -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Squid-3-2-1-Reverse-Proxy-TCP-MISS-403-suddenly-appearing-for-one-cache-peer-tp4661218p4661380.html Sent from the Squid - Users mailing list archive at Nabble.com.
