web - How does nginx view the client's http head?

Question

The server uses nginx, how to check the user's http request header?

Answer 1

nginx has no necessary connection with the user’s http request header.

Where do you want to watch it? What do you want to see specifically?

On the browser, open firebug to view the network request. The request header and receiving header are clear at a glance.

On the server, just use a programming language to view server variables. For example, use phpinfo();

in php
