.htaccess and its importance

.htacess is a filed used by Apache Web server software to effect various configurations to the directory where it is located. It is a hidden file in unix based systems (since its name starts with a dot), and is placed in the root of the directory in which it is supposed to alter the configurations of the web server to allow or limit services. It is basically a file that contains coded information that guides the server on how to execute various functions.
