Update to DNN/Evoq Url Redirect Provider for Multi-Portal Installations

11 May

One often overlooked free utility for DNN/Evoq are the open-source DNN Extension Url Providers. These providers are there to help with social URL's and URL redirects. The URL Redirect provider is a must-have solution for those migrating from other platforms into DNN as it provides a method to easily add complex URL redirects into your system for old URLS. Even for those that are working under the Evoq URL provider. I was made an administrator of this particular product more than 2 years ago, however, we haven't had much of a need to add features until today.

The setting change itself is quick and harmless, simply change the value in Host Settings are you are done. Well, come to find out it isn't exactly that easy.
