title: Server Sent Events Apache configuration
body: <p>I'm running a web application using server-sent events (eventsource).  I've been working to properly set up the apache and PHP configuration files so that the program will accommodate all of my users and not timeout.  I've already set the timeout to an appropriate amount of time in both PHP and apache, but I'm worried about the Server limit, Max Clients, and Max Requests Per Child.  I need to connect around 500 users to the php file that runs the eventsource and run a PHP script every time a message is sent to the server.  The eventsource file seems to take up about a 1/4 MB of ram and a negligible amount of processing power.  Can someone explain what these limits do, and advise me on how best to set them?</p>
