I run a virtual CentOS 5 server with Apache 2 and PHP under FastCGI, using mod_fcgid. I've built an application which relies heavily on Ajax, and in one case uses a popup with PHP flushing to allow the application to work in realtime during a long time.
The issue is that when I connect to one ajax-script I'm locked to that script until it is finished. The same goes for the popup. I don't seem to be able to serve more than one request at a time.
I read in another post that it's most likely the client (Firefox) that causes the issue, but Firefox "network.http.max-persistent-connections-per-server" is set to 10.
How can I allow either the browser or the server (whichever is causing the issue) to accept more than one connection?
