Std.Http.Server.Guard.rateLimitedTracking

fn

rateLimitedTracking: Int -> Int -> Int -> fn(Std.Http.Server.Route.Request, fn(Std.Http.Server.Route.Request) -> Std.Http.Response) -> Std.Http.Response

This is a callable function.

What it does

A rate limiter remembering at most peers peers.

The table is bounded because a server that stays up meets an unbounded

number of addresses, and one that remembered each would grow with every one

of them. The peer seen least recently is forgotten to make room, and starts a

fresh window when it returns: the answer it would have had once its window

ended. A refused peer counts as seen, so a flood of new addresses cannot

push a peer that is being refused out of the table and hand it a new window.
