Website developers are aware of the usefulness and multi-functionality of the .htaccess file. With the help of this file, you can make various useful settings. It is enough to set a certain command only in this file on the server, and all the functions and settings of the site will change dramatically. If we paraphrase the well-known folk wisdom as follows: "One in the field is a warrior", then this will apply to the .htaccess file in the first place.

You can read about what a .htaccess file is here: What is an .htaccess file and how to create it.
In this article, I would like to draw attention to one useful rule for your site. This rule removes file extensions from the URL (browser address bar). Such a rule can be easily organized using .htaccess, adding only a few lines of code to this file.
This can be useful in order to make the addresses of your pages in the Internet browsers of users more beautiful and attractive. For example, the URL: , looks more aesthetically pleasing than the URL: .
Thus, from the address bar of the browser that your visitors see, you can remove any file extensions by writing the following code in the .htaccess file:

https://p-qc.com/about

p-qc.com/about.php

 

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php

Just replace the file extension: php, with your extension, say: html.
Upload the .htaccess file to the root directory of your server, and .htaccess will remove the extensions you specified from the address bar.

Just before you change something in the .htaccess file, be sure to make a backup copy of this file, in case something goes wrong. Be careful with .htaccess, without having some knowledge with this file jokes are bad, you can completely disrupt the performance of your site.
