Introduction

Greetings, readers! We are delighted to present an informative article on Nginx Get Server Name Variable. In today’s rapidly growing technological era, it is crucial to have a better understanding of web servers. Nginx is a widely used open-source software that serves as a reverse proxy, load balancer, and web server. With the Nginx Get Server Name Variable feature, website administrators can easily retrieve the server name that processed the current request. This article is aimed at providing a comprehensive guide on Nginx Get Server Name Variable and its benefits and drawbacks.

What is Nginx?

Nginx is a lightweight, high-performance web server that is designed to handle a large number of concurrent connections. It has become a popular choice among website administrators due to its efficient architecture, fast performance, and low resource utilization. Nginx is widely used as a reverse proxy, load balancer, and web server.

What is Get Server Name Variable?

Nginx Get Server Name Variable is a feature that allows website administrators to retrieve the server name that processed the current request. This feature is useful in cases where a web server is running multiple virtual hosts or websites on the same IP address. By default, Nginx uses the server_name directive to handle incoming requests. However, in some cases, the server_name directive may not work as expected. In such cases, the Get Server Name Variable comes in handy.

How does Nginx Get Server Name Variable work?

When a request is received by Nginx, it is first processed by the NGINX Core. The Core Module then passes the request to the HTTP Module, which determines the server name and location of the request. If the request matches a server block, Nginx retrieves the server name from the server_name directive. If the server_name directive is not set or does not match the current request, Nginx uses the Get Server Name Variable to retrieve the server name that processed the request. The Get Server Name Variable provides the administrator with the name of the server that processed the current request.
