I'd like to know how to count the currently live sessions I have on mt tomcat site? Is there a function on tomcat that will give me the correct information? Or will I have to implement my own solution here?
Kieran, the Servlet API once included a class called HttpSessionContext with methods that would have answered your need, but that class has been deprecated since version 2.1 with 'no replacement planned'. It was considered a security risk to provide this capability.
You will probably have to write code of your own for this purpose unless Tomcat specifically provides something (I don't use Tomcat).
