1) Configure an application to use a manifest and window.applicationCache
2) Download initial cache, everythings works fine.  Server returns an ETag or
Last-Modified date within the header.  Also has headers to disable cacheing.
3) Cache is updated, but the one or more of the resources aren't
4) WebKit requests a resource sending up If-Modified-Since and If-None-Match
header headers.
5) Server returns a 304 Not Modified.
6) WebKit makes another request (goes back to step 4) this process will go on
in an infinite loop.
