The SEO redirect module was first created by us in 2012 when we “converted” a client website from PHP to DNN. Because the existing website ranked quite well in google we needed a way to add mapping for redirects from the old pages to the new ones.
Over the years we have add more functionality to the module and its interface and we now use it on most of our websites.
This module is open source. We've published the source code on GitHub.
