Creating an alternate path for a page

WordPress add a rewrite rule to a page to accept a GET variable

It is possible to add a filter to the_content that takes the query_var (in this case ‘uuid=237237’) from the url and appends it to any outgoing links. But that is beside the point. Because if the link leads to a place outside the current WordPress install the query_var will be lost anyway, even if the … Read more

Redirect old query string URLs to new add_rewrite_rule URL
