I have used your plugin on many sites in the past and it always works great. This time, I have an issue I haven't come across before.
My customer has .com and .net versions of their domain, and both show up in Google results due to how their prior site was set up. The new WordPress site is using .com, with .net "parked" in cpanel. The redirect plugin works great when you click on a Google result referencing the .com, but when you click on a result that uses the .net, it doesn't redirect and instead goes to the original link, resulting in a 404.
Is there a way to allow the plugin/Wordpress to recognize that the .net version is also associated with the site, since the REQUEST field uses relative and not absolute links?
