title: Asynchronous web service call in ASP.NET/C#
body: <p>We have an application that hits a web service successfully, and the data returned updates our DB.  What I'm trying to do is allow the user to continue using other parts of our web app while the web service processes their request and returns the necessary data.</p>
  
  <p>Is this asynchronous processing?  I've seen some console app samples on the msdn site, but considering this is a web form using a browser I'm not sure those samples apply.  What if the user closes the browser window mid request?  Currently we're using the Message Queue which "waits" for the web service to respond then handles the DB update, but we'd really like to get rid of that. </p>
  
  <p>I'm (obviously) new to async requests and could use some help figuring this out.  Does anyone have some code samples or pertinent articles I could check out?</p>
