How to Customize Error Messages for Your Site

There are two main styles of error messages you may encounter. The first is the standard form, which looks something like:

File Not found
The requested URL domainname/filenamme.html was not found on this server.

The second type comes in a variety of forms, but is customized by the webmaster. For example:

Sorry
We're sorry, but the requested URL does not exist. Please e-mail support@domain.com if you need further assistance.

Such messages are called error documents, and are web pages designed to give a polite explanation for error conditions. These error conditions generate numbers which are used to refer to the appropriate error condition. Some of the most common messages are as follows:

Error in Client



400 Bad syntax

401 Unauthorized

402 Not Used (Payment Granted)

403 Forbidden

404 Not Found

Error in Server



500 Internal Error

501 Not Implemented

502 Overloaded

503 Gateway Timeout

How to Customize Error Messages

First, create the HTML page you want to use as your error message.
Upload it to your www directory.

Next, go into your .htaccess file (or create one) and add lines which specify the substitution.
Here are three examples of specifying error documents which will be called for a given error condition (note you can use relative or absolute addressing):



ErrorDocument 401 http://domain.com/nopasswd.html

ErrorDocument 403 /forbidden.html

ErrorDocument 404 http://www.domain.com/nofile.html

Mime Types

You can add mime types to your .htaccess file with a line like:

AddType text/html .txt
