Are the URLs in a HTML 5 manifest file case sensitive?
===

Assume I have the following URLs:

-  Home/Index
-  Home/IndexOffline

Assume I have the FALLBACK section in my manifest defined as follows:

FALLBACK:

Home/Index Home/IndexOffline

Now, if I go offline, and request Home/Index browser will serve Home/IndexOffline for me, but if I'm still offline and I request the same URL (Home/Index) with different permutations (i.e. home/Index, hOme/InDex, etc), the browser will not serve Home/IndexOffline.  

After reading numerous articles, none of them talk about case sensitivity in regards to resources listed in the manifest file.  Is this expected behavior?  Is there a way I can address the issue with out having to list every permutation for a given URL?
