Does recycling the IIS7 application pool kill any

问题:

Does recycling the IIS7 application pool kill any currently executing requests? Or does it wait for all requests to complete (like a drain-stop)?

I don't want the recycling rules to cause intermittent errors from my WCF sites.

Thanks

回答1:

No.

By default, the WWW service establishes an overlapped recycle, in which the worker process that is to be terminated is kept running until after a new worker process is started.

This is from the Documentation for IIS6 and I am sure it applies for IIS7.

If your web service requests are long-running, you might consider increasing the shutdown timeout.

Yes. Recycling an application pool causes the WWW service to shut down all running worker processes that are serving the application pool, and then start new worker processes.
