WebKit supports multipart/x-mixed-replace as long as the content type doesn't
change (14149) or as long as it's not used through an XMLHttpRequest (14392):

The multipart/related (7168), multipart/mixed (9389)  and multipart/alternate
(no bug filed; please consider filing one) content types are not supported yet.

I'm not sure the best way to implement support.  At minimum you will need a
MIME parser.

I would take a look at how .webarchive files are loaded and mimic that.  In
theory, you shouldn't have to worry about the cache as long as all of the
resources fit into memory.  However, I think there may be an issue with
subresources (such as CSS files) on the page not being cached properly for
future reloads when coming from a webarchive (12605).
