What happens to requests when tomcat stops

Question

What happens to http requests that are being processed when you stop or restart tomcat in the "normal" way? Will they be processed until the response is finished or are the http-threads interrupted? Is there a way to configure graceful stopping?

Answer 1

Tomcat supports unloadDelay which waits till the configured time for unloading servlets.

This should configured in context.xml as follows:

<context unloadDelay="10000">
