Hi MustphaBassim,

Browsers tipically open multiple TCP sessions to a server when transferring data, so it might happen that some of those sessions go to a server and some to another. When you consider authentication, the server you authenticated to allows you to see the content, but the other does not. That might be why you're getting redirected to the login page.

So I would suggest having a persistence profile in place (maybe based on source address, maybe cookie). Want to try that?

[Edit: the pool has 1 member, so forget the idea 😞 ]

Hi Mustpha,

You can take a concurrent packet capture from both the client and server side to confirm what is really going on.

You can decrypt the traffic as described in this article here:
