How useful is Response.IsClientConnected?
<p>I was wondering if anyone had experience they could share using the Response.IsClientConnected property as a performance optimization for asp.net websites.</p>

<p>The reason I ask is that I am a bit skeptical on how effective it would be in real life scenarios. I understand the concept of checking the value before performing a large task but I just can't see how useful this would be as clients could disconnect at any point time.</p>
