irule for URL redirection and response content patience page

HTTP::redirect

issues a 302 (Temporary Redirect). Since the URL has been decommissioned you will want to use a Permanent Redirect (301). Permanent redirects will instruct clients and search engines alike to go directly to the new location in the future.

To get the iRule to issue a permanent redirect use:

HTTP::respond 301 Location "http://www.newdomain.com/newpath"
