Recently we had a Website that was redone from a large static site to a dynamically driven site in ASP.Net. The original site was heavily indexed by the major spiders on the Web, we did not want to lose the reference links in the engines and wanted to make sure the link clicked on would go to an appropriate paged in the site. In this article we cover how to create a document mapper so the old URL is redirected to the new related page within the new site.
