Full ACK. Especially, the relevant data uris like data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAAuCAIAAABmjeQ9AAAARElEQVR42mVO2wrAUAhy/f8fz+niVMTYQ3hLKkgGgN/IPvgIhUYYV/qogdP75J01V+JwrKZr/5YPcnzN3e6t7l+2K+EFX91B1daOi7sAAAAASUVORK5CYII= match the specification's regular expressions for unquoted url characters [1]. That said ... while standard conformance is nice here, if others have the feeling that we should quote them nonetheless, I do not see an issue with quoting them. > Besides the other theories advanced, might it be sporadic ResourceLoader > mis-minification?

The referer is empty for ~97% of affected requests. The chain of requests looks like this: 1. Client fetches some page (like http://pt.wikipedia.org/wiki/Copa_do_Mundo_FIFA ) 2. Client fetches resources for this page (like http://bits.wikimedia.org/pt.wikipedia.org/load.php?[...] with referer http://pt.wikipedia.org/wiki/Copa_do_Mundo_FIFA ). 3. Client fetches urls with data uri appended (like http://pt.wikipedia.org/wiki/data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAABkAQAAAABvV2fNAAAADUlEQVQIHWNoYBgWEACJ5TIB0K9KcAAAAABJRU5ErkJggg== with empty referer). Thanks, Christian [1] Well ... both of them. In [2] (normative) the regular expression [!#$%&*-\[\]-~] is used while [3] (also normative :-/ ) uses [!#$%&*-~] . So they differ in \ handling. But regardless of the choice of the above variants, the above url is matched by any of them.
