What is htaccess? Everything about .htaccess file Print

The .htaccess file, known as “hypertext access,” is a configuration file used on web servers. It allows you to modify the server’s behavior for specific directories or files, overriding the default settings defined in the main server configuration.
The .htaccess file is plain text in a website’s directory (Public_html). It can control various aspects of website functionality, such as URL rewriting, access control, redirections, MIME types, error handling, and more.

Some common use cases for .htaccess include:

URL rewriting: You can use mod_rewrite module directives to rewrite URLs and create search engine-friendly URLs or redirect requests to different files or directories.
Access control: You can restrict access to specific directories or files based on IP addresses, user agents, or authentication requirements.
Redirection: You can redirect requests from one URL to another temporarily or permanently.
MIME types: You can define custom MIME types for specific file extensions.
Error handling: You can customize the error pages displayed to users when encountering specific HTTP errors.
Some other uses of the .htaccess file:

Add redirections for specific URLs
Load custom error pages, like 404 pages
Force your site to use HTTPS instead of HTTP
Password-protect specific directories on your server
Prevent hotlinking

It’s important to note that not all web servers support .htaccess files. They are specific to the Apache HTTP Server and its variants like Apache Tomcat. Other web servers, such as Nginx, have their methods of achieving similar functionality.
When working with .htaccess files, it’s crucial to be cautious, as incorrect configuration can cause issues with your website. It’s recommended to have a backup of the original file and test any changes thoroughly.
.htaccess File Location

Where is the .htaccess file located?

.htaccess file is located in the Public_html folder.
Apache (the software that powers your web server) or some other web server is configured to hide all files named .htaccess. Why? The files have essential configuration information and can be used to compromise your server.
Although the file is hidden, the .htaccess file location is most commonly found in your website’s public_html folder.
