Host Header Rewrite

Overview
Host header rewriting enables you to rewrite the host header to the actual origin domain when the origin domain is different from the acceleration domain in the load balancing task.
Directions
1. Log in to the EdgeOne console. Select Origin Configuration >Rule Engine on the left sidebar.
2. On the rule engine page, select the target site and click 
﻿
 to configure host header rules as needed.
3. On the rule engine page, select Host for the match type and Rewrite host header for the action, and configure other parameters as needed. Click Save and publish or Save only.
Note
 Supported match types: "Host".
