.htaccess is a small text file that's installed either directly inside a domain folder or inside a subfolder to inform the server how it should handle requests when a site or a folder that is part of it is accessed. Lots of commonly used scripts such as Joomla™ and WordPress use an .htaccess file. If you get loads of fake traffic to your Internet site, for example, you'll be able to block the access of certain IP addresses and third-party sites, or you could request the visitor to enter a username and a password to be able to view the content. You could also set up URL forwarding or use custom error pages for your website, prevent other websites from linking to your content directly and from using your account’s traffic quota, etc. An .htaccess file offers you significantly more control over your Internet sites and the way they function.
