Geoblock exception based on user agent



We have Geo-blocking enabled for one of our apps and want to allow access from a third party tool that has a very specific user agent. Is it possible to allow requests from a geo blocked location when the user agent matches a particular string?


Thank you.

  • You can do it with an iRule which checks the User-Agent Header to be the one you want to white-list and then unblocks that request using ASM::unblock

    Here is a sample iRule (replace 'My Magic User Agent' with User-Agent you need):

      foreach {viol} [ASM::violation names] {
        if { $viol eq "VIOLATION_ILLEGAL_GEOLOCATION" } {
          if { [HTTP::header "USER-AGENT"] contains "My Magic User Agent" } {

    Hope this helps,


    P.S. Remember to enable 'Trigger ASM iRule Events' in your policy properties!
