Trigger Once per session for specific client iRule

Good evening all,   I am looking for a way to do a "one time" trigger within an iRule.   Scenario:   User accesses site and if the html text "banana" is seen, log something, insert something...

All variables have scope of TCP session. Or do you mean users browser session? You could add in a session cookie to help you with that.

 

Also when you say 'html text "banana"' do you mean if you see the word 'banana' in the content of an HTTP response?

 

A bit more info and we can give you some code to illustrate.....

Create a stream profile str_banana that looks for string 'banana', then attach an iRule as follows;-

when STREAM_MATCHED {
   if {![HTTP::cookie exists 'banana']} {
       Insert session cookie
      HTTP::cookie insert name 'banana' value "1"
      HTTP::cookie httponly 'banana' enable
      log local0. "Banana seen for this session"
   }
   STREAM::disable
}
