How to change relative url paths in external CSS?

I am using Juice to try and inline font-awesome CSS.

Given I have a html file called 'test.html' which includes the following:

And I then run the following juice command (which I ran at the following directory: C:\Users\admin\Desktop):

juice test.html test-out.html

I get the following error:

Error: The file C:\Users\admin\Desktop\https:\cdnjs.cloudflare.com\ajax\libs\font-awesome\3.1.0\font\fontawesome-webfont.eot was not found!

It is clear that the error states that it is trying to reference a file that does not exist locally, and so it shouldn't.

Now it appears the issue is related to the external css in that it references @font-face's relatively. Which (I think) means that when Juice tries to inline the css, it uses the local relative path, causing the the error.

I have tried using the --web-resources-relative-to and --web-resources-rebase-relative-to flags to see if this would fix the issue but they cause any other references to behave differently causing different errors.

**I should also make it clear that I need to make this work without modifiying the html. Is there anything in Juice that I am blindly missing that would help me resolve this issue? or is it not possible to change the relative path of external file/css references**

Reproduce the case with test.html, the linked Font Awesome stylesheet, juice test.html test-out.html, and the --web-resources-relative-to and --web-resources-rebase-relative-to flags. Trace how the external stylesheet's relative font URL is resolved; done means the command handles that URL without modifying the HTML while preserving other resource references.
