GentleSource Short URL Script
Short URL Script allows you to have a URL shortening service under your own domain. The script can create shorter URLs that do not break in email messages or mask your affiliate links. As a site owner, you can use the script for managing downloads, masking URLs, and keeping track of how many times a link has been clicked. The script also has a simple API that allows third party tools to create short URLs. New modules allow you to convert links into affiliate links.
