Pre-10.5 equivalent of 'WebVeiw :: - (NSString *)mainFrameURL'

[Stefan]

Hi,

didn't use Cocoa for some time. Thus, here is a simple question...

I need a pre-10.5 equivalent of WebView's

	- (NSString *)mainFrameURL

API docs explain, that this method is functional equivalent to

	[[webView mainFrame] loadRequest:]

But, obviously, it is not.
	
Thx,

stefan
