How to use .htaccess
‘.htaccess’ is the filename in full, it is not a file extension. For instance, you would not create a file called, ‘file.htaccess’, it is simply called, ‘.htaccess’. This file will take effect when placed in any directory which is then in turn loaded via the Apache Web Server software. The file will take effect over the entire directory it is placed in and all files and subdirectories within the specified directory.
