I can get to a site form my Squid server directly using lynx http://my-URL , ie not using squid as the proxy, just to prove the connectivity exists. Lynx connects fine to the site - its a Weblogic portal
When I try the same site from client with the squid machine as a proxy I get a squid error indicating that the destination site refused the connection from Squid.
The squid server is a RHEL5.5 server.
The error is something like
The following error was encountered: Connection Failed
The systen returned: (13) Permission denied
The squid access.log just indicates a TCP_MISS. It's as if the destination site knows its been accessed by squid and is not allowing ?
Sounds like you need to toy around with your squid ACL rules. I bet you that's the issue in there. Hopefully your squid.conf is well commented so you can figure it out easily enough. I suspect you'll want to take a look at ACL rules that refer to your LAN and HTTP connections.
Resolved now - it turned out to be an SElinux issue.
