NimbostratusJsession cookie insert TCL error
All,
Notice that I am getting a ton of TCL error messages on the F5's. I seen in the past that this can cause resource issues. I see that the irule works, but just not sure of this TCL error.
Thanks,
Bryce

Hey Bryce. It's interesting that the line of code mentioned in the error "persist add uie [string tolower [HTTP::cookie "JSESSIONID"]] 3600" doesn't actually exist in your rule (the error includes the 'add' subcommand). Is this just a copy and paste error?
Also, is there a reason you are lowering the JSESSIONID value?
Ganno_161963I am experiencing the same error but I believe what Bryce missed is the HTTP_RESPONSE portion of the iRule. Here is mine:
when HTTP_RESPONSE { Check if the JSESSIONID cookie is present in the response and has a non-null value if { [string map {\" ""} [HTTP::cookie "JSESSIONID"]] ne "" }{ Persist on the JSESSIONID cookie value for X seconds persist add uie [HTTP::cookie "JSESSIONID"] 3600 } }I have searched other posts and I do have a default pool assigned to the virtual server. Help is always appreciated.
