Maximum Active Sessions in Apache 2.4 Web Server

what is the perceived problem that you are trying to solve?  Sessions is normally either ON or OFF and session state is stored either on the server or in the users browser

There's no Apache limit to sessions.

Sessions are managed by other means.

As David asked above, state exactly what problem you're trying to solve + exactly what error you're seeing + likely someone can assist you.

I assume you are referring to maximum concurrent connections which shared hosts use to limit connection per tenant

As far as I can tell it is MaxClients in httpd conf

Thank you everyone for your response.  I understand all your responses, however I'm attempting to limit the number of allowed simultaneous session requests.   I know Tomcat has the maxActiveSessions tag which is set in the context.xml file and was researching to see if Apache has a similar setting in the httpd.conf file.
