Introduction

Greetings to all our tech enthusiasts out there! Do you want to know about a powerful feature in Nginx servers that can significantly impact your website’s performance? Look no further because we are here to discuss the “Nginx catch all server listen” feature. This feature is widely used to improve website performance, but it also has some drawbacks that we will cover in this article. So sit back, relax, and get ready to dive into the world of Nginx servers and their catch all server listen feature.

What is Nginx Catch All Server Listen?

Nginx is an open-source server software that is widely used to power websites across the internet. One of its unique features is the catch-all server listen. When Nginx receives an HTTP request that does not match any server name, it redirects the request to the catch-all server listen. This server then handles the request by serving a default page or returning an error message if the requested page doesn’t exist.

This feature is essential when hosting multiple websites on the same server, as it ensures that any requests that don’t match the specified server names are handled correctly. It also offers improved website performance by reducing the number of errors with broken links or incorrect URLs.

How to Set Up Nginx Catch All Server Listen

Setting up Nginx catch all server listen is straightforward. First, add a catch-all server block to your Nginx configuration file. This block should be placed after all other server blocks and should have a server_name of “_”. This wildcard character matches any server name that does not match a specific server block.

Here is an example of what the configuration block would look like:

Server Block	Configuration
Example Server Block	server {    listen 80;    server_name example.com;    location / {       root /var/www/example.com;       index index.html;    } }
Catch All Server Block	server {    listen 80;    server_name _;    return 404; }
