Insert HTTP headers when accessing a Webtop link

If your webtop link is going to a page sitting behind your F5, then you could use your iRule to add headers to the request.

If the link goes to an external site, then I don't think you'll be able to insert any headers, as there's not way for the F5 to intercept the traffic. Even with a 30x redirect too, it wouldn't force the browser to send the desired headers on the request. You would need to link to a url on the F5 that could proxy the request to the real server so you can inject those headers.
