Hi Daniel,

Thanks you for manual, but this was not what I need.

I need a way to drop session without show any page.

I tried to use irule event with "drop" or "ACCESS::session remove" like this:

when ACCESS_POLICY_AGENT_EVENT {
 
    log local0. "log"
    drop
#  ACCESS::session remove
}

But the result is the same.

Best regards

can you share why you want this?

 

because in general you just want to show something if it fails. total reset / drop will just cause someone to be left behind wondering what happened, pressing F5 and starting over.

 

perhaps looking at ACCESS::disable can get you somewhere, that should stop APM from acting. but still perhaps share your overall question / case so someone can think on that.
