I am not asking the web server which is provided by the cPanel. I know the web server is Apache web server. Today I have stopped Apache and still I could access both cPanel and WHM. If Apache is what serves cPanel, then the WHM and cPanel will not be available when the Apache service is down. So could someone please explain how cPanel works independently. Is there any native web server used in cPanel?
We have our own daemon, cpsrvd, which handles cPanel & WHM requests. It is primarily configured via Tweak Settings, and a few other interfaces, in WHM.
