You can set custom pages to display when web requests fail. When a web request fails, the user is automatically redirected to the custom page. This topic describes how to customize an error page.
Background information
Alibaba Cloud provides two types of pages for status codes: default pages and custom pages. The following example uses the 404 status code to illustrate the difference between a default page and a custom page.
Default: If an HTTP response has a 404 status code, the server returns the default 404 Not Found page.
Custom: If an HTTP response has a 404 status code, the user is redirected to a custom 404 page. You must provide the full URL of the redirect page.
Alibaba Cloud provides a public 404 page. This page is a public resource and is free of charge.
Custom pages are your own resources. These pages are charged based on standard data transfer billing.
For more information about why 404 pages are returned, see Causes of custom 404 pages.
