How can I release 'request' in my project that using ARC?

Question

As a beginner of iOS developer. I use ARC in my project. And I even use ASIHttpRequest to make some work easier. As you know, ASIHttpRequest not support ARC. I've added the -fno-objc-arc compiler flag to make it work. Now, here is my question. How can I release the 'request' object if some of my code like this :

NSURL *url = [NSURL URLWithString:@"http://allseeing-i.com"];
   __block ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
   [request setCompletionBlock:^{
      NSData *responseData = [request responseData];
   }];
   [request setFailedBlock:^{
      NSError *error = [request error];
   }];
   [request startAsynchronous];

And, there is no 'alloc', so even under a non-ARC environment there is no need to release... — SEG

Its my understanding that the compiler does the right thing with NSObjects when mixing ARC and non-ARC code.

Based on the naming conventions for Cocoa methods, responseData should be a non-owning reference. Thus, you should not be responsible for retaining/releasing it. The request object owns it.
