Bug Report

What did you do?

Add an external load balancer above PD and enable the internal proxy.

What did you expect to see?

The internal proxy can work.

What did you see instead?

Return 508 error.

Because we check if Via header is existed to prevent the loop, but the external proxy maybe already have this header. Once the request is sent to the PD follower, it will be rejected due to the check.

What version of PD are you using (pd-server -V)?

master
