Access URL Redirection

Overview

EdgeOne Nodes redirect the client requests request URL to the target URL by responding to 3XX status codes. This feature can change the URL redirection that originally needed to be generated and returned by the origin server in your business scenario to be directly constructed and returned by the EdgeOne edge nodes, reducing the network latency of following the origin-pull and the load of the origin server generating the URL redirection, and improving the access performance of the client.

Use Cases

The following are common Applicable Scenarios for Rewrite access URL:
Migration of website or reconstruction: When a website undergoes migration or reconstruction, the URL structure may change. To maintain the validity of old links, you can use URL redirect to redirect old URLs to new URLs, ensuring that users and Search Engines can smoothly access the new resources.
Geographical location or Device Type orientation: Based on the user's geographical location or device type, you can use URL redirect to guide users to different resources or pages. For example, provide optimized mobile pages for mobile device users, or provide different language versions of pages based on the user's region.
Temporary maintenance or activity page: When a website is undergoing temporary maintenance or hosting a specific event, you can use URL redirect to guide users to the maintenance notification page or activity page, thereby improving the user Experience.
