URL shortener for ASP.net

I like this idea, very nice. Shortened URLs have been around before Twitter was popular, and I have used them on occasion (I like them for sending links to Google Maps locations, since those can be unwieldy). But they do present a few problems.

Your little control is very nice, have you given much thought to handling query string parameters or other such things? Eventually, if your site has enough pages shortened, you will simply end up with really long URLs regardless, especially if your website tries to keep things RESTful.

Of course, the only "problem" is that if someone simply has a long domain name, it will only help so much (like "codinghorror.com," that's just a lot longer than "tr.im").

Just as a contrived example, here is your shortened URL for this page, right below the shortened URLs from a few of the other shortening sites, including a custom one I made:

   http://tinyurl.com/ncxsvk
   http://tr.im/oZa9
   http://tr.im/aspshorts
   http://clipperhouse.com/-m

Notice which one is longest? Granted, you do lose out on knowing the *real* URL, but when people are using this for Twitter every character counts. Either way, I like the idea!
