The .htaccess file is a file found in Apache servers that allows you to manipulate the behaviour of the server. A very common use is to create custom error messages for server errors. Examples of such errors are "404 Not Found" (say when you click on a broken link), and the "500 Internal Server Error" (a script failed). Most hosts allow you to have your own .htaccess file, and so now we will look at only one of the things we can do with a custom .htaccess.
