Note: Using $array(variables) is much faster if you need to create AND delete them on each single request (aka. using per-request variables). Personally I always use four different kinds of $array(variables) in my own iRules. $static::global(), $session(), $conf() and $temp(). The $static::global() will store global configuration, the $session() variables will persist for an entire TCP session. The $conf() variables may changed/deleted as needed and $temp() variables will be flushed on each single request (or on demand if the containig data is large). This simple procedure makes the handling of $variables a no brainer even for the most complex iRules...
