This is not a URL shortener like TinyURL or Bit.ly. It is a temporary URL generator. You enter a URL, and a new Temporary URL (tURL) is returned. When that tURL is followed, only the content of the original URL is returned - not the URL itself. After the tURL has been access just once, it disappears forever. I originally built this as a way to conceal pre-signed URLs for S3 files, but have since moved to another method. However, I thought this was a cool concept so I ported it to use Amazon SimpleDB and put it up on my personal server (which happens to be on Amazon EC2).
