Apache is a commonly used web server software. Many websites use Apache as their web server. In Apache, you can specify which types of files the server will process through configuration, such as HTML, PHP, JavaScript, etc.
In many websites, we will find that their servers can only access PHP files and cannot access other types of files. This is because these websites are specifically configured in the Apache configuration file so that the server can only process PHP type files.
So, why is there such a configuration? What is the point of Apache only having access to PHP?
1. Improve website performance
The first thing to understand is that various modules and extensions of Apache will consume server resources, especially when processing a large number of requests. If Apache processes all types of files, the server will need to devote more resources to processing, which will undoubtedly reduce server performance.
If you restrict Apache to only process PHP files, other types of files will no longer occupy server resources. This can improve the processing performance of the server and make the website more stable when the number of visits is large.
2. Improve website security
Another reason is to improve website security. If Apache processes all types of files, it may face some security threats.
For example, if Apache processes uploaded image files, hackers can attack by uploading malicious code. And if only PHP files are processed, hackers cannot attack in this way.
In addition, specifying Apache to only process PHP files can also avoid some path traversal attacks and code injection vulnerabilities, and improve the security of the website.
3. Strategies to support website architecture
In some websites, there are various combinations and diversified configurations such as nginx reverse generation, Apache processing PHP, Tomcat processing Java, cdn acceleration, etc., among which Apache only processes PHP as a strategy to ensure the stability of the architecture.
For PHP language parsing, Apache is a very good basic support. Since good support only involves one language and allows it to be processed professionally, it can not only improve performance, but also improve the robustness of the entire architecture system. sex.
Summary:
With the above reasons, we can understand why many websites only allow Apache to process PHP type files. This configuration can improve the processing performance of the server and the security of the website, and avoid the existence of some attack methods and vulnerabilities. Of course, this does not mean that other types of files cannot be processed, but that these files need to be processed through other servers.
