iRule to Rewrite User Agent Header

If you would like to use a traffic policy which I think would be a better approach:

1. From "Local Traffic ›› Policies ›› Policy List" Create a new policy

2. In that policy create a new rule with the following condition and action:

    

   • HTTP Header named User-Agent contains any of XXX at request time

      

   • Replace HTTP Header named User-Agent with value YYY at request time

      

   For XXX, add each of your specific strings (MSIE 7, ...), I'm not sure if this field accept regular expressions but you can test the regex suggested by Stanisla.

    

   Replace YYY with your replacement string.

    

3. Save and publish your policy, then associate it with your VS.
