Just an aside. Although doing the globs above is quick and easy (and performs well too), you will run the risk of breaking your site a little if you get the irule wrong when editing it on the fly (changing logic is always interesting ;) and if you have a lot of sites it will quickly get to be quite long...

 

 

To reduce risk of breaking migrated apps wth the change to add new ones I'd use a datagroup and a lookup via the [class ...] commands.

 

 

You could always use the ProxyPass iRule from the codeshare too... New sites are then just a datagroup edit away. (In fact id recommend reading the ProxyPass iRule anyway. It will show you a lot of stuff thats possible with an iRule).
