Introduction
Greetings to all developers and website administrators out there! Welcome to the ultimate guide on Apache Change Server Name Header. In this article, we will dive deep into everything you need to know about this topic.
For those who are unfamiliar, the Apache HTTP Server is the most widely-used web server software out there, used by millions of websites worldwide. One of the most important aspects of any web server is its ability to communicate with clients, and for that, it uses HTTP headers.
One such header is the Server name header, which is used to identify the web server software being used by a website. For instance, if you visit a website and look at the headers, you might see something like:
Server: Apache/2.4.41 (Ubuntu)
As you can see, this tells us that the website is running on Apache version 2.4.41 on an Ubuntu server. However, in some cases, you might want to change this header for various reasons, which is where Apache Change Server Name Header comes in.
What is Apache Change Server Name Header?
Apache Change Server Name Header is the process of modifying the Server name header sent by the Apache web server. This allows website administrators to hide the web server software being used, or to present a different server name altogether.
This can be useful for various reasons, such as:
- Security: By hiding the web server software being used, attackers won’t be able to target any known vulnerabilities in that software.
- Branding: By presenting a different server name, you can promote your brand or company instead of the web server software.
- Compliance: In some cases, you might need to comply with certain regulations or policies that require you to hide or modify the server name header.
How does Apache Change Server Name Header work?
Apache Change Server Name Header works by modifying the ServerTokens and ServerSignature directives in the Apache configuration files.
The ServerTokens directive controls what information is sent in the Server name header. By default, it is set to “Full”, which means that the header will contain the Apache version number and operating system information. However, it can be set to “Prod” or “Major” to hide this information, or to “Min” to only show the Apache version number.
The ServerSignature directive controls whether or not the Apache server version and other information is displayed in error messages generated by the server.

Frequently Asked Questions
1. What is the default value of the ServerTokens directive?
The default value of the ServerTokens directive is “Full”.
2. How do I change the value of the ServerTokens directive?
You can change the value of the ServerTokens directive in the Apache configuration files. Look for the line that says “ServerTokens Full” and change “Full” to “Prod”, “Major”, or “Min”.
3. What is the default value of the ServerSignature directive?
The default value of the ServerSignature directive is “On”.

Some common alternatives to Apache web server software include Nginx, Microsoft IIS, and Lighttpd.
9. Can I use Apache Change Server Name Header with SSL/TLS?
Yes, you can use Apache Change Server Name Header with SSL/TLS. However, you will need to configure your SSL/TLS certificates properly to ensure that they match the server name you are presenting.
10. Can I use Apache Change Server Name Header with virtual hosts?
Yes, you can use Apache Change Server Name Header with virtual hosts. However, you will need to make sure that you are modifying the correct configuration files for each virtual host.
11. Will Apache Change Server Name Header affect my website’s performance?
Apache Change Server Name Header should not affect your website’s performance significantly, as it only modifies a small part of the HTTP response. However, keep in mind that every modification to the HTTP response can potentially affect performance.
12. Can I use Apache Change Server Name Header with reverse proxies?
Yes, you can use Apache Change Server Name Header with reverse proxies. However, you will need to make sure that the proxy server is configured to pass on the modified server name header.
13. Is there any way for attackers to identify the web server software being used if the server name header is hidden or modified?
Yes, there are other ways for attackers to identify the web server software being used, such as examining the HTTP response headers for other clues, analyzing the behavior of the web server, and exploiting other vulnerabilities in the website’s code.
Conclusion
As we have seen, Apache Change Server Name Header can be a useful tool for website administrators who want to hide or modify the server name header sent by the Apache web server. However, it is important to weigh the advantages and disadvantages carefully before making any changes to your website.
Remember that hiding or modifying the server name header can have unintended consequences, such as compatibility issues or suspicion from clients. Furthermore, it is not a foolproof way to secure your website, as attackers have other ways of identifying the web server software being used.
However, if you do decide to use Apache Change Server Name Header, make sure to follow best practices and configure your web server properly to ensure that it is both secure and functional.
