Can tomcat send out event about persistent connection being closed?

[M M <me...@yahoo.com>]

I am using Tomcat 5.5 and I would like to bind the HttpSession lifecycle with its underlying persistent connection lifecycle. Partically, if the persistent connection is closed due to connectionTimeout or client program exits, I would like to invalid the client's HttpSession, and if the HttpSession timeout, I would like to close the persistent connection too. 

I know the APIs to control the HttpSession lifecycle, but I am wondering if there is any API in Tomcat to allow me to control the lifecycle of the underlying persistent connection.

Your help is greatly appreciated.

Monica

A couple of issues:

1) There may not be an underlying persistent connection, if the client
chooses not to use keep-alives.

2) There will likely be more than one connection associated with a given
HttpSession.  For example, content embedded in a page will usually
result in multiple simultaneous connections being establshed by the
browser to retrieve said content as quickly as possible.
