I'm new to iRules, i'm looking for a iRules who can can return an URI from a VIP

If you want an iRule that sends a canned HTTP response, you can use the HTTP::respond command (Click here).

Here is an example:

when HTTP_REQUEST {
   HTTP::respond 200 "some html content"
}

If you want to send a 302 redirect, you can use:

when HTTP_REQUEST {
   HTTP::redirect http://somehost.example.com
}

If this isn't what you're looking for, can you elaborate?

Thanks,

Aaron
