title: Web Service and Events
body: <p>I am unsure of whether this is possible and have conducted a handful of quick searches on the web and I don't think it is but here goes.</p>
  
  <p>I have a web service (old school .asmx) which retrieves a list of items from a database. I want my client app to be notified if there are any items to be processed INSTEAD of the client app every so often making a request to the web service. Is this possible?</p>
  
  <p>I know this is possible via WCF (duplex communication) however due to complications I can't use that approach.</p>
  
  <p>Oops I just realised that I would also require the web service to poll itself or get something to call it asynchronously? Don't think this is a good solution...</p>
  
  <p>Thanks in advance, Onam.</p>
