Detect session hang and kill it

Question

Hi all,

I have an asp.net page that runs certain algorithm and returns it's output. I was wondering what will happen and how to handle a case where the algorithm due to a bug goes into infinite loop. It will hog the cpu and other sessions will be served very slowly.

I would love to have a way to tell IIS, if processing Algo.aspx takes more than 5 seconds, kill it or something like that.

Thanks in advance

Answer 1

There is no such thing in IIS. What you can do instead is to perform the work in a background thread and measure the time it takes to complete this background task and simply kill the thread if the wait time is longer than expected.

You may take a look at the WaitHandle.WaitOne method which allows you to specify a timeout for waiting for a particular event to be signaled from a background thread for example.

Answer 2

Set the ScriptTimeout property. It will abort the page if the time is exceeded. It only works when the debugging property is set to true, though.
