I'm fairly new to regular expressions, so I'm having a bit of trouble. I am using the URL Rewrite Module within IIS7/Win2K8.

I am trying to come up with a regexp to rewrite part of the following "friendly" URL:

/City-State/ (example: /Cleveland-OH/)

as the following:

doit.aspx?CITY=City&STATE=State (example: doit.aspx?CITY=Cleveland&State=OH)

The CITY portion of the friendly URL will be of variable length, then a hyphen, then STATE portion (will always be the two-character state abbreviation).

I thought about keying off the hyphen, but that would cause problems should there ever be a hyphenated city name. Instead, I was wondering if it is possible to parse the string for the last two characters?

I suppose I could work the other way and just scan the string for the final hyphen (in the event that there are more than one).

Any thoughts on the best way to handle this?
