I recently redid an ExpressionEngine site that was not using template routes for a blog, so the blog URLs were like this: http://mywebsite/blog/detail/url-title-here
After the redesign, I created a template route and removed the 'detail' segment changing the URLs like this: http://mywebsite/blog/url-title-here
Both URLs are now accessible though, so I want to redirect all of the old URLs to the new ones without 'detail' in the URL.
How can I achieve this? Thanks.
