ccing Darin since it's WebKit API, although I don't think we need to wait for his ok for this since it's just adding a similar function to an API he just reviewed.

the URL can be generated from the WebFrame, so it's redundant here

> Source/WebKit/chromium/src/StorageAreaProxy.cpp:89

nit: don't line wrap this

According to Dr Barth the allowLocalStorage() implementation should be using securityOrigin() and not URL.  There are case where the two can differ and we definitely don't want to let a page get around the user's local storage settings by faking out the url.

So the old code was calling frame->document()->url(), hence why I moved it to do the same.  Does securityOrigin() return the whole url, or only scheme+host+port?  If it's the latter, then that wouldn't work if the user has a content setting for a url that has path for example.

Security restrictions at a finer granularity than a scheme+host+port don't work.

ok so I tried to set content settings policies for a url with a path, and that didn't work.  so it looks like it's just for hostnames then, in which case using securityOrigin should be fine.  however, that should be done in a separate cl, in case that has any side-effects.  this change has others that depend on it, and once they're committed, reverting this won't be possible without reverting the chorme side.

R=me. I agree that changing the url/securityOrigin behavior should be a separate patch.
