You can use NSURLConnection. You should use implement the NSURLConnectionDataDelegate protocol and use the NSURLConnection class.

-(void) requestPage
{
    NSString *urlString = @"http://the.page.you.want.com";
    NSURL *url = [NSURL URLWithString:urlString];

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLCacheStorageAllowed timeoutInterval:20.0f];


    responseData = [[NSMutableData alloc] init];
    connection = [[NSURLConnection connectionWithRequest:request delegate:self] retain];
    delegate = target;
}


-(void) connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{   
    if ([response isKindOfClass:[NSHTTPURLResponse class]])
    {
        NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse*) response; 
        //If you need the response, you can use it here
    }
}

-(void) connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
    [responseData appendData:data];
}

-(void) connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
    [responseData release];
    [connection release];
}

-(void) connectionDidFinishLoading:(NSURLConnection *)connection
{
    if (connection == adCheckConnection)
    {
        NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];

        //You've got all the data now
        //Do something with your response string


        [responseString release];
    }

    [responseData release];
    [connection release];
}
