Reading data from the web

Hi student-dev-ers,

I'm trying to give my application access to information online (so that it can automatically detect software updates). However, I'm having no luck actually getting it to read the data. For instance, I adapted the code at http://developer.apple.com/documentation/Cocoa/ Conceptual/Strings/Articles/readingFiles.html to get:

NSString *path = @"http://www.graphsketcher.com/update/ com.robinstewart.GraphSketcher.plist.txt";
NSError *error;
NSString *stringFromFileAtPath = [[NSString alloc]
initWithContentsOfURL:[NSURL URLWithString:path]
encoding:NSUTF8StringEncoding
error:&error];
if (stringFromFileAtPath == nil) {
// an error occurred
NSLog(@"Error reading URL at %@\n%@",
path, [error localizedFailureReason]);
}

Which results in:
"Error reading URL at http://www.graphsketcher.com/update/ com.robinstewart.GraphSketcher.plist.txt
(null)"

Despite the fact that the URL is readily accessible via web browser. Have any of you done this kind of thing successfully?

Thanks,
Robin
