Web performance issue for server behind ASA

Hi all,

I am trying to isolate an issue with one of our web servers.  I have a ASA 5510 behind which I have a Windows 2008R2 IIS8 server.

The problem is that even though the site works, everytime I go to the page it seems to stall.  Only when I refresh it does the page come up.  This happens intermittently.  The ASA code I am running is 8.0.4.28.

Does anyone know if this is a known issue in this code and upgrading it to 8.0.5 will resolve this issue?

Also any other ideas would be welcome.

Thanks.

Hey,

This issue might be related to packets exceeding MSS value when trying to access web page across the firewall. Try the workaround in following link:-

Hope this helps.
