.htaccess is a small text file that's placed either directly inside a domain folder or inside a subfolder to tell the web server how it should manage requests when a website or a folder that is part of it is accessed. A lot of famous scripts including WordPress and Joomla™ use an .htaccess file. If you get a great deal of fake traffic to your website, for example, you may block the access of certain IP addresses and third-party websites, or you may request the visitor to type in a username and a password in order to view the content. You could also set up URL forwarding or use personalized error pages for your site, prevent other sites from linking to your content directly and from using your account’s traffic quota, and so forth. An .htaccess file gives you much more control over your Internet sites and the way they work.
