This is temporary as to not break things during the transition, right?  If so, add a FIXME.  If not, are we going to leave 2 ways to do this?  I'm not completely against it, but lets not turn the WebKit API into Perl.

Sorry, I should have explained this better.  I intend to keep an accessor to the global CookieJar on WebKitClient.  That way, simple apps like DRT/TestShell can continue to talk to the platform layer for cookies.  This is important since our plan for porting DRT to Chromium's WebKit API involves exporting a GetWebKitClient function from the chromium code base.  It would be awkward for DRT's WebFrameClient to have to turn around and ask the platform layer for cookies.

In such a case, wouldn't the cookie jar just be a singleton?

I'm not sure I like the idea of adding "there's more than one way to do it" to our WebKit API unless absolutely necessary.  It's also bad if our tests are hitting one code path and production is using another.

WebKitClient is where we place singletons.  The idea here is that the embedder may wish to have a different cookie jar for a particular frame.  This is all to avoid having to pass a WebFrame parameter to the WebCookieJar methods.  I could do that, but that seems like a layering violation.  This was my solution to avoid that layering violation.

It is not that different of a code path, and the differences would still exist if we parameterize WebCookieJar methods with a WebFrame.  The getCookieJar method helps minimize the difference.

Fair enough.
