With GoToOurPlace.com finding a solid user base, users have begun to request changes to the URLs that they have created. As such, I developed a set of extensions to the tool that enable users to modify, delete and track the usage of the short URLs that they create. In order to make the process of mapping URLs to users as seamless as possbile, I employed the Single Sign On functionality provided by SWGfL's 'SWGfL Merlin' product. SWGfL Merlin's SSO mechanism is powered by standards-based, open source SSO service, Shibboleth. Any SWGfL Merlin user can now log in to GoToOurPlace.com using their SWGfL Merlin login, and create, edit, delete and track short URLs that are mapped to their SWGfL Merlin account.
