What is Nginx Server Response?

Nginx is a high-performance open-source web server that is used to serve websites. When a website is accessed, the web server sends a response to the user’s browser. The server response is a set of headers that provides information about the website to the browser. The server response includes information such as the content type, server version, and status code.

The server response is an important factor in website performance, security, and search engine ranking. By changing the server response, you can improve website performance, prevent malicious attacks, and optimize your website for search engines like Google.

How to Change Nginx Server Response

Changing the Nginx server response is a simple process that involves modifying the Nginx configuration files. The configuration files are located in the Nginx installation directory. To change the server response, you need to modify the server block of the Nginx configuration file.

Step 1: Locate the Nginx Configuration File

The Nginx configuration file is usually located in the /etc/nginx directory. You can use the cd command to navigate to the directory.

Step 2: Modify the Server Block

The server block is where you can modify the server response. The server block is located in the Nginx configuration file under the http block. You can modify the server block by adding or modifying the server_tokens directive.

The server_tokens directive controls the server response. By default, the server response includes the server version, operating system, and other information. You can modify the server_tokens directive to remove or change this information.

Here’s how to modify the server_tokens directive:

Directive	Value
server_tokens	off

By setting the server_tokens directive to “off”, you can remove the server version and operating system information from the server response.

Step 3: Reload Nginx

After making changes to the Nginx configuration file, you need to reload Nginx for the changes to take effect. You can use the following command to reload Nginx:

sudo service nginx reload
