.htaccess is a small text file that's installed either directly inside a domain folder or inside a subfolder to inform the web server how it should address requests when an Internet site or a folder which is part of it is accessed. Numerous popular scripts including WordPress and Joomla™ use an .htaccess file. If you get a lot of fake traffic to your website, for example, you'll be able to block the access of specific IP addresses and third-party Internet sites, or you can request the visitor to type in a username and a password to be able to see the content. You may also set up URL forwarding or use custom made error pages for your website, prevent other websites from linking to your content directly and from using your account’s traffic quota, and so forth. An .htaccess file offers you far more control over your websites and the way they perform.
