First, you need to set up a stream profile in the VS, then, set up this iRule:

 

when HTTP_REQUEST {
    STREAM::disable
    HTTP::header remove "Accept-Encoding"
}

when HTTP_RESPONSE {
    if { [HTTP::header "Content-Type"] contains "text" } {
        This code will create a random number and append query string to the original source file.
        STREAM::expression "@global/js/alertnotificationmanager.js@global/js/alertnotificationmanager.js?rand=[expr rand()]@"
        STREAM::enable
    }
}

I think this should work! 🙂 Regards.
