Cool stuff, Daniel_Wolf!!

I've been playing around as well, and I like this as a startoff point, but find nits in each result that I  then refine. For example, on your challenge 3 I'd make sure to prevent injection by adding -- to the command, and since there is no glob style matching in the example, i'd remove the -glob flag. But if I was going to do matching, I'd make sure to set the nomenclature of my pools to match the host in some way so I can make that iRule extremely simple.

One catch though...shouldn't the string map in Challenge 2 be reversed? if the server is newhost, then that needs to be mapped back to oldhost, right? I think in a couple runs I made on other stuff it gets the string map backwards as well. Something to watch for...
