Question

In my iPad app, I am creating an NSURLConnection, and when a valid URL is provided, then I can read the returned data from the host. However, when I put in an invalid URL, the app crashes when I try to make the request.

What is the easiest way to determine if a URL is pointing to a host that can be accessed?

I saw that Apple has a reachability tutorial, but that does not allow you to check if a specific host can be reached.

Thanks.

NSURLConnection delegate methods:

-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
    NSLog(@"ERROR with theConenction");
    [connection release];
}
