In this repository, you may find customized HTTP error documents that can be used in place of the web server's simple hardcoded error responses an existing default error document configured in the main server's configuration file.
An error page informs a visitor when there is a problem accessing your website. Each type of problem has its own status code. For example, a visitor who enters a nonexistent URL will see a 404 error, while an unauthorized visitor trying to access a restricted area of your site will see a 401 error.
Basic HTTP error messages are automatically provided by the web server, however, these generic error responses may be less uninformative and can be intimidating to some visitors. You may wish to display custom error messages which are either friendlier, or in some language other than English, or perhaps which are styled more in line with your site layout.
Customized error messages can be defined for any HTTP status code designated as an HTTP error condition, beginning in 4 or 5. Additionally, some useful server environment variables can be used (if available) to further customize the error documents based on the values of these variables.
