I actually tested a much smaller file on another server and it seemed to work. Originally I was testing an 18 MB file and this was failing with web sharing but succeeding on other servers. I had a co-worker try this 18 MB file out on his web sharing machine and his seemed to work. At that point I swapped it out for a 6 GB file and then it happened again.

Can you quickly confirm for me the version of Apache you're talking to on Port 127.0.0.1? IIRC, Apache 1.x has a known limit of 4GB despite it's HTTP 1.1 'compliance'
If you're using apache 2 and greater, then this may well be a bug in NSURLDownload (though the fact that it works with other servers is intriguing).

When downloading a large file (~6 GB) either on 127.0.0.1 or another machine on the same subnet via web sharing, NSURLDownload seems to hang at some point in the middle of the download. This doesn't seem to happen when using other servers. Also Safari seems to be able to download the file just fine. The client is using 10.6.2. I've tried web sharing on the local machine (127.0.0.1 and 10.6.2) and also on a remote machine using 10.5.8. I've written a simple tool to test this that looks like:
- (void)downloadDidFinish: (NSURLDownload *)download { NSLog(@"downloadDidFinish");
// release the connection [download release]; }
- (void)download: (NSURLDownload *)download didFailWithError: (NSError *)error { NSLog(@"download didFailWithError\n"); // release the connection [download release];
// inform the user NSLog(@"Download failed! Error - %@ %@", [error localizedDescription], [[error userInfo] objectForKey:NSErrorFailingURLStringKey]); }
- (void)download: (NSURLDownload *)download didReceiveResponse: (NSURLResponse *)response { NSLog(@"download didReceiveResponse\n"); }
- (void)download: (NSURLDownload *)download didReceiveDataOfLength: (unsigned)length { NSLog(@"download didReceiveDataOfLength %lld\n", length); }
int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; MyHandler *theHandler = [[MyHandler alloc] init];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL: [NSURL URLWithString: (NSString *)@"http://10.147.27.137/~elliott/winxp.hdd"]
cachePolicy: NSURLRequestReloadIgnoringCacheData/*NSURLRequestUseProtocolCachePolicy*/
timeoutInterval: 60.0];
// create the connection with the
request
// and start loading the data NSURLDownload *theDownload = [[NSURLDownload alloc] initWithRequest: theRequest delegate: theHandler];
[theDownload setDestination: (NSString *)@"/Users/elliott/Documents/testdownloadfile" allowOverwrite: YES]; CFRunLoopRun(); [pool drain]; return 0; }
At some point I stop getting download didReceiveDataOfLength and never get a downloadDidFinish nor didFailWithError. Am I doing something wrong?
