Re: CSS Unable to Maintain Sessions

Ray,

the only way to be sure is to capture a sniffer trace.

Capture the client -> css + css -> web + web --> css +  css--> app flows.

See where the RST or FIN is coming from.

For the CSS, there is no Web, no APP, no sessionid ....

Just flows with a default idle timeout.

You can try to increase the idle timeout with the command "flow-timeout-multiplier 50' on every content rule and group.
