title: NSURLConnection hits didFailWithError when the URL actually exists
body: <p>I am trying to send a simple NSURLConnection request:</p>
  
  <pre><code>- (void) sendHTTPRequest:(NSString*)urlString
  {
  NSLog(@"SendHTTPRequest: %@", urlString);
  
  @try
  {
      NSURL *fileURL = [NSURL fileURLWithPath:urlString];
  
      // Create the request.        
      NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:fileURL            cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
  
      NSURLConnection *connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];
      if (connection) {
          receivedData = [NSMutableData data];
      }
      else {
          // Inform the user that the connection failed.
      }
  }
  @catch (NSException *e)
  {
      NSLog(@"Exception: %@", e);
  }
  }
  </code></pre>
  
  <p>It calls back to:
      - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error</p>
  
  <p>with an error of: Connection failed! Error - The requested URL was not found on this server.</p>
  
  <p>However, this url does work.  I can access it with my browser with no issues.
  What am I missing?</p>
