Trimmed URLs flagged as invalid URLs

[The_Magistrate]

I have mod_pagespeed installed as an apache mod. When using the trim_urls filter, a url to an external site -- e.g. ​http://wordpress.org -- gets rewritten to //wordpress.org automatically.

When a user clicks on the link, an email gets sent to the Wordpress Admin stating:

A user tried to go to ​http://alexcline.net/wordpress.org/ and received a 404 (page not found) error. It wasn't their fault, so try fixing it.
They came from ​http://alexcline.net/index.php

Technically, //wordpress.org is a valid external URL and works correctly in a user's browser. It would be nice if I didn't have to get notifications about these URLs.

Core doesn't send emails about 404s. Sounds like you have a plugin doing this.

WordPress doesn't modify the links, If you're using mod_pagespeed, the trimming will occur after it's out of WordPres's hands.

If a user is clicking the link and it's directing the user to ​http://alexcline.net/wordpress.org/ then either their browser doesn't support the trimmed URL support, some Javascript is messing with the trimmed url's, or there's a bug in the url trimmer.
