Summary:  Always the same data with [NSURL 
loadResourceDataNotifyingClient:usingCache:NO]

Original Submission:  I always get the same data, when doing:


- (void)fetch
{
        [anURL loadResourceDataNotifyingClient:self usingCache:NO];
}

- (void)URLResourceDidFinishLoading:(NSURL *)anURL
{
        NSLog([[anURL resourceDataUsingCache:YES] asciiStringValue]]);
}


I mean, as I understood the documentation, when calling 
-loadResourceDataNotifyingClient:usingCache:NO, with NO as the cache flag, it 
should load the data in the background and put it into its cache. So that when 
-URLResourceDidFinishLoading: is called, one can retrieve, what has been loaded 
by calling -resourceDataUsingCache:YES. (How could one retrieve, what has been 
loaded otherwise?)
But I always get the same data and I think, I know why: In 
GSHTTPURLHandle.m:283, the URL-handle is not put into the cache, because 
'usingCache' is NO. But using the cache and filling the cache is not the same, 
but seems to me as if treated the same way here.
I have removed this condition and it works at my place.

Thanks for the bug report ... I believe I have fixed the problem in CVS.
The fix I used was to modify NSURL.m to ask for a handle which uses the cache 
irrespective of the flag supplied to 
-loadResourceDataNotifyingClient:usingCache:, also to try to return cached data 
if the flag is YES
