Changing post's URL and then setting it back causes redirect loop
|Reported by:||vbuterin||Owned by:|
This morning, I changed the URL of one of my posts, but then changed my mind and set it back. When you change the URL of your post, WP automatically creates a redirect from the old page to the new page, which is good, but in this case it led to an unintended consequence: after I changed the link from A to B and then back to A, it set up a redirect from A to B and a redirect from B to A, causing anyone trying to access A or B to end up in a redirect loop between the two (or possibly it created a redirect loop from A to A; I'm not sure). It should check for such loops when you update the URL to avoid this problem.
