Well, that worked wonderfully! Thanks again for your help. Unfortunately, and as always, the plot thickens.
The guy I had originally discussed this change with didn't give me all the facts. Here be the situation:
Any http request coming into "http://www.site1.org/forms" must be somehow be redirected to "http://www.site2.com/forms".
The problem is that "/forms/" has subdirectories. Therefore I don't think a simple redirect will do the trick. Also, since it's the URL which needs changed and not just the uri, a uri rewrite won't work either. I tried it but was unsuccessful. Is there a way to do some kind of partial URL rewrite while still leaving "/forms/..." and trailing subdirectories intact?
For example, the iRule you put together for me would take a request for "www.site1.org/forms/sub1/sub2" and redirect it to "www.site2.org/forms" without keeping "/sub1/sub2".
Is this even possible?
