Custom Error Messages
The .htaccess file can be used to generate customised error pages.
To setup a customised error message in the event that a visitor requests a file from your website that does not exist or has been removed, you need to add the following line to the .htaccess file:
ErrorDocument 404 http://www.yourdomain.com.au/notfound.html
Where 'notfound.html' is the file that is displayed containing the error message. This file should be placed in the public_html directory.
