Fair enough. What I'm looking for at a minimum is the headers
associated with each HTTP response.
You'd get at those through the resource load delegate. When a resource
is loaded the delegate receives an Objective-C method call, named:
webView:resource:didReceiveResponse:fromDataSource:
The response argument is an NSURLResponse object. After determining
that it's an HTTP response, using -[NSObject isKindOfClass:] it can be
cast to NSHTTPURLResponse and you can use methods such as -
[NSHTTPURLResponse allHeaderFields] and -[NSHTTPURLResponse
statusCode] on it.
It would be nice to also be able to extract any HTML meta tags and
have access to those as well.
That can be done with the DOM API. Something like this:
DOMNodeList *metaElements = [[webView mainFrameDocument]
getElementsByTagName:@"meta"];
NSUInteger count = [metas length];
for (NSUInteger i = 0; i < count; ++i) {
DOMElement *metaElement = (DOMElement *)[metaElements item:i];
NSString *nameAttribute = [metaElement getAttribute:@"name"];
// ... more work here
}
FYI, some of the things you mentioned from the Firefox dialog are
things that are either part of the networking library or part of the
browser application proper, and not controlled or tracked by WebKit.
