An .htaccess file is a text file which incorporates directives that tell a web server how to act in particular situations. It must be placed into the folder where these directives should be executed. Many script-driven apps employ such a file to work efficiently - WordPress and Joomla™, in particular. You can use this sort of a file with custom made content as well and do a lot of things - block an IP address, a whole network or certain websites from accessing your site, set customized error pages that shall appear instead of the server-generated ones if a visitor encounters some error on the website, redirect a domain or a subdomain to a different web address, create a password-protected area plus more. With an .htaccess file, you will have significantly better control over your world-wide web presence.
