// Prepare for the response back from the server    
NSHTTPURLResponse *response = nil;
NSError *error = nil;

// Send a synchronous request to the server (i.e. sit and wait for the response)
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

// Check if an error occurred    
if (error != nil) {
    NSLog(@"%@", [error localizedDescription]);
    // Do something to handle/advise user.
}

// Convert the response data to a string.
NSString *responseString = [NSString alloc] initWithData:responseData  encoding:NSUTF8StringEncoding];

// View the data returned - should be ready for parsing.
NSLog(@"%@", responseString);
