Hi Thomas,

no problem :). I'm happy that you took time to think about my problem and even if the iRule was not working, you pushed me in the right direction. I am just playing around with the iRule and figured out, that is does not work because [LB:server addr] has no value.

Regarding your latest suggestion, I am not sure if the event LB_SELECTED will work for the [HTTP:uri] command. I'm afraid it will work for [LB:server add] but not for [HTTP:uri] because the reference of [HTTP:uri] says:

Valid Events:
CACHE_REQUEST, CACHE_RESPONSE, HTTP_CLASS_FAILED, HTTP_CLASS_SELECTED,  HTTP_REQUEST, HTTP_REQUEST_DATA, HTTP_REQUEST_SEND, REWRITE_REQUEST_DONE, SERVER_CONNECTED

What can I do? Do I have to check two events? Is that possible?

Thanks, Thorsten

Yes you can check two events in a same iRule. With that you define a flag if your first event is OK and you'll be able to know in LB_SELECTED if everything was OK before.
