Rewrite profile - any better way?

Hi,

Assuming that using Rewrite profile is only option (even if worst one) how to solve missing trailing / issue?

If URI Rule is like that:

• Client: http://site.com/old/
• Server:

and user will send request without trailing /, like /old

URI rule will not catch such request.

Some web servers (for sure my IIS) is sending back redirect when receiving such request (but I doubt it's standard behavior for all types of web servers?) so client will be redirected to /old/ and then URI rule fires.

But it's not perfect - if backend server will not send redirect then everything breaks up. Even if it will send then it is not best situation as /old request are still reaching backend.

I am right now using iRule I found on DevCentral to fix such requests at VS level, because iRule is executed before Rewrite profile it seems to be working solution.

But maybe it's not a right approach, maybe I am missing something important that could break backend server functionality somehow?
