Getting a quick response to NSUrl by sending a soap message to the .NET web server

Question

I am new to web services. I need to get information from a .NET web server. For this, I use the following code:

-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
    [webData setLength: 0];

}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
    [webData appendData:data];
    if (data) {
        NSLog(@" bcxbm,xcm,xcmcmx,b data consist %@",data);
    }
    else {
        NSLog(@"not exist");
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"UIAlertView" message:@"<Alert message>" delegate:self cancelButtonTitle:@"Retry" otherButtonTitles:@"Cancel", nil];
        [alert show];
        [alert release];
    }

}
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{

    NSLog(@"ERROR with theConenction");
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    NSLog(@"DONE. Received Bytes: %d", [webData length]);

I can get the information, but I need to check it. If there is no connection, I need to start Alertview. For this, I have the code:

-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
    {
        [webData appendData:data];
        if (data) {
            NSLog(@" bcxbm,xcm,xcmcmx,b data consist %@",data);
        }
        else {
            NSLog(@"not exist");
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"UIAlertView" message:@"<Alert message>" delegate:self cancelButtonTitle:@"Retry" otherButtonTitles:@"Cancel", nil];
            [alert show];
            [alert release];
        }

    }

I check by deleting the connection. But it does not cause any warnings. After a while, it will display Error in connectionin the console. But it takes a lot of time. Is there any other possibility besides this? How to display a warning when there is no connection?

Can anybody help me?
