.htaccess is a small text file that's placed either directly inside a domain folder or inside a subfolder to inform the server how it has to handle requests when an Internet site or a folder which is part of it is accessed. Many famous scripts like WordPress and Joomla™ use an .htaccess file. If you get a lot of fake traffic to your Internet site, for instance, you may block the access of certain IP addresses and third-party Internet sites, or you could request the visitor to input a username and a password in order to view the content. You could also set up URL forwarding or use custom error pages for your site, prevent other websites from linking to your content directly and from using your account’s traffic quota, and so on. An .htaccess file will give you significantly more control over your websites and the way they work.
