KeepAliveTimeout 0 in apache webserver

Question

I am running apache webserver in centos 7. Configured KeepAliveTimeout 0 in httpd.conf file. I thought based on this configuration, every tcp connection is alive until we force close. but count is gradually decreased when application is idle.

then what is KeepAliveTimeout 0 meant by.? what do i need to change for TCP connection alive..?

For reference i have attached screenshot of the server

Click F12[DeveloperTools] in browser and go to Network Tab. Now reload the web page and check request headers & response headers. You should see keep alive parametre in both headers.

yes. i can see from both headers. but my question is when we set keepalive =0, Is all tcp connections active until we force closed or it will be auto close once session expired..? – Manivannan Thirugnanam Jun 29 '17 at 09:16

Client must request KeepAlive, setting it just in the server does not force client connections to use keepalive.

How browser concludes here the request should (get method) be keepalive or non-keepalive – Saikiran Nov 25 '17 at 06:09
@Sunny in a request header called "Connection", only valid for http/1.1 iirc. – Daniel Ferradal Nov 27 '17 at 12:44
