Quick Tips


Is The User Still There?

There are times when it's necessary to do rather complex queries in an ASP page. While you can warn a user that a request might take a while, that doesn't always stop them from clicking on it and then not waiting to get the results.

Before starting that next call to your DB for the even more data you've just decided you're going to need, you might want to just pop your head up and check to see if the user still cares about the result.

By default, ASP scripts continue to run to completion even if the user has left. By checking the Response.IsClientConnected propery, you can check to be sure the user still wants the result before embarking on that CPU-killing query you need to run to get it.

Microsoft has a nice simple "How To" on the topic in their Knowledge Base: Q182892.
