Jan 11, 2007iRule help
I am having the same problem with persistence on the following iRules.... I am currently using the first of the two.
The application I am working on is an applet program. The applet sessions on the server timeout in 60 minutes. For some reason, sometimes one of my reqests does not stick, and it is persisted to the wrong server. This causes my applet application to Have a SessionExpired exception.
I am working with f5 customer support and they have not come up with anything in the TCPdumps yet.
Is the following the correct way to set to > 60 minutes for the entry to stay in the persistence table ...?
Does anyone have any thoughts or suggestions, I am really stuck.
Thanks in advance...

I've had similar problem regarding redirecting the traffic based on URI and we've observed, that sometimes there is problem with set command, which does not fill the variable...if { [persist lookup uie $resPers] equals "" } {
if { [persist lookup uie [HTTP::cookie "JID"]] equals "" } {

It could also be your TCP idle timeout (set in the TCP profile that's applied to the virtual server). The default on that is 300 seconds, so ensure that you have lengthened that as well.
