title: ASIHTTPRequest: prioritizing requests
body: <p>Using <code>ASIHTTPRequest</code>, can i prioritize the requests or specify their order? </p>
  
  <p>I'm using <code>ASIHTTPRequest</code> along with <code>ASINetworkQueue</code>. For example, i send Request 1, 2, 3, 4, 5, .... By default <code>ASIHTTPRequest</code> support 4 concurrent connections, so as a result Request 5 starts when any one of the previous requests are completed. Now, in my case, i may need to post a Request (say A) before Request 5. Request A maybe triggered as a result of Request 1 (<em>success</em>). </p>
