I am trying to see, what is the web-server name of a particular website.
http://browserspy.dk/webserver.php
When I searched I got response as
Server: cloudflare-nginx
I know nginx and cloud-flare but I never heard a web-server named cloudflare-nginx
.
Usually I get "nginx" as the webserver if website is powered by "nginx"
Can someone explain this Server: cloudflare-nginx means ?
Most likely, Cloudflare has a custom built Nginx webserver running their services which they've renamed to cloudflare-nginx.
You can change the server header output this way:
