Error handling is what the Web server does in the event a request is made resulting in an error. For example, if you try to go to a page that doesn't exist on a server you will see the all too common ``Error 404: File not found.''. In this menu you can list the error number and tell Apache to load a specified Web page or display a specified message if this error is encountered. Below are a list of common error codes and their meanings. You can refer to the Apache documentation for a complete list of error codes.
| Error Code | Meaning |
| 301 | Permanent Redirect |
| 302 | Temporary Redirect |
| 401 | Bad Password |
| 403 | Forbidden / Access Denied |
| 404 | File Not Found |
| 405 | Method Not Allowed |
| 500 | Internal Server Error |
