           Summary: REGRESSION: cache management from  changeset 36109 lead
                    to errors
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Major
          Priority: P1
         Component: Page Loading
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: max at ac-mb.info


I found two other related bugs in there: 20959 and 21207.
Since changeset 36109, when a page is loaded, there are some times where a
cached file, generates a warning in the inspector console :
Resource interpreted as other but transferred with MIME type xxx
xxx can be javascript or css at least, maybe other types.
This is always when the new protocol is used as we can see the request headers
If-Modified-Since and If-None-Match. The server response is correct.
The real problem comes because the concerned file is not correctly interpreted
and for javascript can produce unexpected result. It does not look as if the
file is really not interpreted, but rather as if some condition/event are not
raised like window.load etc.

 I can't find a way to reproduce the first incorrect caching handshake (timeout
or what) but as soon as it occurs it its reproductible on each page load unless
a full reload is made where state is reset to correct behavior.
