Apache Server Header Codes: Everything You Need to Know

Introduction

Hello there! If you’re reading this article, chances are you’re interested in learning more about Apache server header codes. In today’s digital age, having an understanding of these codes is crucial for web developers, webmasters, and SEO experts.

Before we dive into the nitty-gritty of Apache server header codes, let’s first understand what an Apache server is and what it does. Apache is an open-source web server software that powers millions of websites around the world. It’s the most popular web server software available and is used by developers to serve web pages on the internet.

Now that we have a brief understanding of what Apache is let’s move on to Apache server header codes.

What Are Apache Server Header Codes?

Apache server header codes are HTTP response headers that provide information about a website’s server and the page being served. These codes are sent by the webserver to client request headers.

When a user requests a webpage from a server, the server responds with an HTTP header. This HTTP header contains information about the server, including the server’s name, operating system, web server software, and more. Apache server header codes are part of this HTTP header and provide specific information about the Apache server.

Types of Apache Server Header Codes

Apache server header codes can be broken down into three main categories:

Code	Description
Server Tokens	Identifies the version of Apache server being used
Server Signature	Provides detailed information about the server software being used
Server Modules	Lists the modules installed on the server

Server Tokens

Server tokens are used to identify the version of Apache server being used. By default, Apache server tokens are set to “Full” which displays the server name, version, and operating system. The other two options are “Prod” which only displays the server name and “Minor” which displays the server name and version number.

It’s important to note that displaying server tokens can be a security risk as it provides attackers with information about the server and software being used. Therefore, it’s recommended to turn off server tokens if you’re concerned about your website’s security.

Server Signature

Server signature provides detailed information about the server software being used. This includes the server name, Apache version, operating system, and more. By default, Apache server signature is set to “On”, which means that this information is displayed in the HTTP header. However, just like server tokens, server signature can be turned off to enhance the security of your website.

Server Modules

Server modules provide a list of all installed modules on the server. This is useful information for web developers who need to know which modules are available and which ones they can use on their website.
