iRule to disable APM not working as expected

May want to try with

when CLIENT_ACCEPTED {
    ACCESS::restrict_irule_events disable
}

which version of TMOS? I experienced having to build in a timer in a similar situation before 11.4.

are you sure there are any requests to other URI also?

when HTTP_REQUEST {
set u [HTTP::header "User-Agent"]
set uru [HTTP::uri]

log local0.notice "user agent: $u and uri: $uru"

    if {[string tolower [HTTP::header "User-Agent"]] contains "mac os x" } {
            ACCESS::disable 

    }   
}

when CLIENT_ACCEPTED {
    ACCESS::restrict_irule_events disable
}

Doesnt work and ltm logging shows only:

It should hit pool configured for the virtual server without creating access session. What do you expect in the logs?

Tested the following iRule with curl

curl -k -L https://10.2.60.70

when HTTP_REQUEST {
  set u [HTTP::header "User-Agent"]
  set uru [HTTP::uri]
  log local0.notice "user agent: $u and uri: $uru"
  if {[string tolower [HTTP::header "User-Agent"]] contains "curl" } {
    ACCESS::disable 
  }   
}
when CLIENT_ACCEPTED {
    ACCESS::restrict_irule_events disable
}
when ACCESS_SESSION_STARTED {
   log local0.notice "Access session started"   
}

The logs doesn't have the Access session started message. Is there anything else done in your iRule?

hey thanks for taking the time to reproduce though my behaviour is different. I've added when ACCESS_SESSION_STARTED and I do see the session. Even when simply trying the [HTTP::host][HTTP::uri] directly from a web browser.

I think it's triggered for the Exchange Web Service(EWS) by the exchange profile attached the access policy. You might see this in the APM logs. If you are using a 11.4 version you might be able to modify the iRule _Sys attached.
