We have a lot of direct mail that need vanity urls. This required constant management of these urls almost every week. We needed to make them case-insensitive due to our audience and some direct mail that somehow got out the door with capitals. We started going down the route of regex “^/(?i)” in front of url to make case-insensitive. The caused a problem because I was wanting power users to be able to manage these redirects in the future through a plugin. I also called our hosting company WPEngine to add the apache/nginx module to make on server side have case-insensitive but because of their standard builds they were not able to implement. So that lead me to find this article that created a plugin that looked for caps and made lower on the init of WordPress. Here is the code below and also link to the source.
