cache manifest absolute url suggestion

Your URL: http://www.w3.org/TR/html5/browsers.html#manifests


Dear Sir / Madam,

This is the first time that I take contact with w3c. Please excuse me if I
am not following the regular contacting path.

I am using html5 cache manifest in my web application and found the
following scenario.

In my html file I have an external link to a style located on an external
domain:

*<link rel="stylesheet" href="//example.com/style.css
<http://example.com/style.css>">*

Here I can use the *//* prefix in the link href for serving my page on both
http and https protocol.


I wish that I can use this possibility in cache manifest.


*CACHE MANIFEST*

*//example.com/style.css <http://example.com/style.css> *instead of
* http://example.com/style.css <http://example.com/style.css>*


In this way, cache manifest and link href are consistent, otherwise there
is no cache if the html file is served on https protocol.


Would you like give some feedback on my suggestion?


Best regards,

Hua
