This is the path, not the url "generated".

I am not sure usemin can do that (maybe you can edit lib/fileprocessor.js file to match your needs).

Else, you can use another Grunt task who can pre or post process HTML file (maybe https://github.com/jsoverson/grunt-preprocess can match your needs?)

https://www.npmjs.org/package/grunt-cdnify with rewrite is what are you looking for.

I think ?__inline=true should be ignored when concating file.

Of course it's ignored, "?" is invalid for a "path". You must use another grunt task for this, which is dedicated for HTML post process.

In this pull request #443 , I just make a little change, and now it works fine for me.

Not sure is the right way to achieve this. The documentation clearly says is a path, not a complete URL.

A right way to improve usemin would be to add a paramater (HTML inline or within the grunt file), something like an URL mask where we could also set a CDN , thats will ne Fan-Tas-Tic !

The problem here is, common.min.css?__inline=true is a valid url , but not a valid file path. To resolve this, I convert the url into a file path by remove the query string in the url.

@ebuildy what you have in mind to set a cdn ?

Added the codereview tag as waiting for a review of #443. Not sure about this.
