Description
Posting this to get some early feedback. Addressing checklist items in follow up commits.
The goal of this PR is to add support for the ability to proxy only the first N connections that get sent to a service, and then otherwise ignore subsequent connections. The intended use case here is to provide a helpful control mechanism for applications with exotic, long-lived application layer protocols for use during development:
to name a few.
