HTTP Error Handling

You can configure Internet Information Services (IIS) to send custom error messages instead of the default HTTP 1.1 error messages. These custom error messages can be mapped to a file name or to a URL.

Error handling

HTTP 1.1 error messages are returned to the client browser in the form of an HTML page that contains a generic message. When a user attempts to connect to a Web site and an HTTP error occurs, a message is sent back to the client browser with a brief description of what happened during the attempt to establish a connection.

This dialog allows you to properly configure custom HTTP Error Pages for your application on the target IIS Server.

Customizing an HTTP Error Page

Use the [ Customize... ] button, the “Customize...” context menu item or press the Space key while an element from the list control is selected.

Caution!When a set of custom error messages is configured at the Web Site level, all directories under that server inherit the entire list of custom error messages. Because of this the two custom error message lists (for the server and the directory) are not merged.

Reset an HTTP Error Page to its default behaviour

Use the [ Set Default ] button, the “Set Default” context menu item or press the Delete key while an element from the list control is selected.
