Rewrite host and URI, then redirect

 

Brilliant - that did it. And that is much simpler than using HTTP::payload as well I would guess which is the path I was about to start down. I knew from the earlier work the values were cached, but I also thought I wasn't able to change them because they were cached. Thanks for the help, and for the schooling! I'm sure I'll find plenty of uses for the techniques I've learned in this thread.
