When forwarding layer 7 service requests using Alibaba Cloud SLB, if you have two domain names under a certain VIP, which are respectively vip.a.com and img.a.com. Now you want to activate session persistence for vip.a.com, but not for img.a.com.
To achieve this, you can select "Rewrite Cookie" mode when enabling session persistence on the console.
In this mode, you can set the cookie name in the response. Server Load Balancer will overwrite the original cookie when it discovers that a new cookie is set. The next time the client carries the new cookie to access the Server Load Balancer, the listener will distribute the request to the previously recorded backend server.
