[webkit-dev] Add HTTP headers to WebView URL request with and without redirection

[David Kilzer]

If you want to do it for every request inside a WebView, why not just implement the resource load delegate method this way:

- (NSURLRequest *)webView:(WebView *)sender resource:(id)identifier willSendRequest:(NSURLRequest *)request redirectResponse:(NSURLResponse *)redirectResponse fromDataSource:(WebDataSource *)dataSource
{
    NSMutableURLRequest *mrequest = [request mutableCopy];
    if (mrequest) {
        [self AppendHeaders:mrequest];      
        return [mrequest autorelease];
    }

    NSLog(@"Could not make mutable copy of %@", [request description]);
    return request;
}
