Tab in the ChangeLog will prevent this from being committed.  I'm surprised the style bot didn't catch that.

This looks sane, although I'm surprised the Qt network layer doesn't do this for you.

r- as this now has to be reworked after fix for 37097 is landed. The same bug (missing feature) cause both xhr and app cache failures. 

Bug 37097 is using 10 as a redirect limit, I'm ok with that instead of 16 proposed as part of this patch.

Krithiga, can you rewor your patch so that it works on top of patch for bug 37097. I think your error handling code and the Skipped list update is still needed.

Thanks for finding this out for us, Laszlo.

QtNetwork is pretty agnostic on this score. It passes back redirects to the client by setting an attribute in the QNetworkRequest:


    \value RedirectionTargetAttribute
        Replies only, type: QVariant::Url (no default)
        If present, it indicates that the server is redirecting the
        request to a different URL. The Network Access API does not by
        default follow redirections: it's up to the application to
        determine if the requested redirection should be allowed,
        according to its security policies.
        The returned URL might be relative. Use QUrl::resolved()
        to create an absolute URL out of it.

So if QtWebKit wants to respect redirects it needs to sanity check them as well.

Thanks for the clarification. This confirms the correctness of webkit approach.

ChangeLog has a small text alignment issue, otherwise looks good. Krithiga, can you fix it ?

This make http/tests/appcache/fallback.html crash 
on the qtwebkit-2.0 bot. Have you got any idea why? 

I tried against Qt 4.6.0, 4.6.2 and 4.7.0, but
they didn't solve this crash.
