CachedStaticFilesStorage chokes on file references that end with a '#' or '?' character

[mkai]

I'm using the "bullet proof" font-face syntax as described here: ​http://www.fontspring.com/blog/the-new-bulletproof-font-face-syntax

It uses two special file references:

url('myfont-webfont.eot?#iefix')
-- for IE support

url('myfont-webfont.svg#svgFontName') format('svg') -- for SVG fonts

During post_process, CachedStaticFilesStorage tries to open these files from disk, including the '?' and/ or '#' characters, which of course fails, and the processing stops.

The desired behavior would be that when trying to open the file from disk during collectstatic, the remainder following a question mark or hash character is stripped ("myfont-webfont.eot"), but that it still gets included into the hashed file ("myfont-webfont.<MD5>.eot?#iefix").

If I remember correctly, a unique id is added as query string in references to external files, and this feature should be kept.

However, the fragment can be preserved.

Actually the unique ID is added to the filename not the querystring.

But other than that you're right, we need to strip the querystring and fragement when trying to access the file but add it later again when rewriting the url() with the filename that includes the hash.
