[Chromium] Unable to repost form data by hitting reload

When the results of a form submission are not in the cache, the user
will see an error page indicating (with a scary warning) that they
would need to hit reload in order to see the page.  However, doing
so does not work.  Instead, Chrome issues a GET request to the URL.

Original bug report:
http://code.google.com/p/chromium/issues/detail?id=28678

Repro steps:
1- Load a page with a HTML form that does a POST
2- Submit the form
3- Go back
4- Clear your cache
5- Go forward
6- Observe the 'Confirm Form Resubmission' error page
7- Hit reload
8- Hit OK
9- Notice that the browser sends a GET instead of a POST

I went about writing a test for this, but sadly it can't work
in DRT or TestShell because neither loads error pages.  As a
result I have no way to simulate the steps from comment #0.
Enabling error pages would interfere with existing tests.

I could modify the layoutTestController to support an option
that would enable error pages, but that seems like a much
larger change that I'd rather defer to a separate patch.

(I'd like to land this so I can backport it to the Chrome 4
branch.)

This sounds reasonable.  Again, my confidence here is low.  Thanks for explaining why this is hard to test.

+ m_frame->loader()->activeDocumentLoader()->originalRequestCopy();

I'd prefer grabbing this object via m_frame->loader()->originalRequest(); but that's not essential.

Oh, good call!  Thanks, I'll do that.
