The interesting parts of now defunct online retailer have been acquired by was a site that I really admired, so it’s good to see their assets go to a good home. Interestingly, I was checking out the site, and noticed that their pages use the extension .gsp, one that I’m not familiar with. I quickly discovered that GSP is, in fact, a system similar to JSP for building template-based Web sites. It looks like the system hasn’t been updated since 1999, so I wonder if is revising the code internally.
