Is the ASIHTTPRequest is not asynchronous?

I am using ASIHTTPRequest to fetch some data from a web service.

I am making requests using a loop.

The problem is that it doesn't seem the request is going asynchronously so that my activityindicator is not working .

Is it true that ASIHTTPRequest is not asynchronous .

or should i use the regular nsmutablerequest to perform asynchronous request .

You should put your request in a download queue, i.e.

ASIHTTPRequest *request = [[ASIHTTPRequest alloc] initWithURL:url];
[request setDelegate:self];
[request setDidFinishSelector:@selector(requestDone:)];
[request setDidFailSelector:@selector(requestWentWrong:)];
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
[queue addOperation:request];
[request release];

Just

[request startAsynchronous];

runs the request on the UI thread, so you should try it with download queue.

For Sync Synchronous

  NSURL *url = [NSURL URLWithString:@"http://allseeing-i.com"];
  ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
  [request startSynchronous];
  NSError *error = [request error];
  if (!error) {
    NSString *response = [request responseString];
  }

Creating an asynchronous request

- (IBAction)grabURLInBackground:(id)sender
{
   NSURL *url = [NSURL URLWithString:@"http://allseeing-i.com"];
   ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
   [request setDelegate:self];
   [request startAsynchronous];
}

- (void)requestFinished:(ASIHTTPRequest *)request
{
   // Use when fetching text data
   NSString *responseString = [request responseString];

   // Use when fetching binary data
   NSData *responseData = [request responseData];
}

- (void)requestFailed:(ASIHTTPRequest *)request
{
   NSError *error = [request error];
}

And there is lot of more options like Queue and many more
