Maximum numbers of tenants acceptable for Restrict-Access-To-Tenants

Question

Hello,

How many tenants/tenant IDs can we add to the Restrict-Access-To-Tenants header for tenant restriction?

I guess there's a limit on this since it affects http header length.

Answer 1

I would look at the V2 that is in preview now which no longer leverages the proxy method instead:
