Nimbostratushow to setup persistence to concatenate jvmRoute with JSESSIONID to generate final SESSIONID
Hi, Can anyone help with how to setup persistence for a request as below:
We are going to be setting a "jvmRoute" variable in tomcat, and need to configure the F5 load balancer to concatenate it...

NimbostratusHi All,
We have similar requirement i.e. to persist at BIG-IP level in this pattern "JSESSIONID.jvmRoute". I would like to know if this iRule below would help us in achieving that goal.
when HTTP_RESPONSE {
if { [HTTP::cookie exists "JSESSIONID"] } {
persist add uie [HTTP::cookie "JSESSIONID"][HTTP::cookie "jvmRoute"]
}
}
when HTTP_REQUEST {
if { [HTTP::cookie exists "JSESSIONID"] } {
persist uie [HTTP::cookie "JSESSIONID"][HTTP::cookie "jvmRoute"]
}
}

sirwinstonHi Ram,
As I indicated Tomcat appends the jvmRoute to the JSESSIONID. Tomcat does not set a separate jvmRoute cookie so [HTTP::cookie "jvmRoute"] will always return an empty string.
Bottom line is that the standard JSESSIONID irule should work fine.
Rgds,

Thanks for quick response, Winston!
I'll implement the above iRule without [HTTP::cookie "jvmRoute"] and post the results. Out tomcat instance already has jvmRoute configured in server.xml file.
