Making asynchronous requests

- (void)requestDone:(ASIHTTPRequest *)request
{
    NSString *response = [request responseString];
    NSLog ( @"Response %@", response );

}

- (void)requestWentWrong:(ASIHTTPRequest *)request
{
    NSError *error = [request error];
    NSLog ( @"Something wrong" );
}

- (void)requestURL()
{
    NSURL *url = [NSURL URLWithString:@"http://allseeing-i.com"];
    ASIHTTPRequest *request = [[[ASIHTTPRequest alloc] initWithURL:url] autorelease];
    
    [request setDelegate:self];
    [request setDidFinishSelector:@selector(requestDone:)];
    [request setDidFailSelector:@selector(requestWentWrong:)];
    
        [networkQueue addOperation:request];
    [networkQueue go];
}
