Changeset 63307 for trunk/src/wp-includes/rewrite.php

Message:

Rewrite Rules: Only a leading www. is optional in url_to_postid().

Fixes the behavior of url_to_postid(), which treated a www. string anywhere in the URL as optional, breaking some URLs. Anchor the string so that is only considered optional when at the beginning of a URL string.

Follow up to [63207].

Props youknowriad, johnbillion, wildworks, irozum, joedolson.
Fixes #65016.
