This middleware provides request throttling to limit the number of requests a given peer may perform per hour/day.
The peer will be identified by its IP address or by a user-supplied identity function. Among other things, this opens the possibility to throttle by path or throttle a service over all clients.
This is still work in progress with a very basic set of functionality. Get in touch if you would like to see additional use cases implemented.
Use it together with the Elli webserver like this:
-module(my_elli_stuff).
-export([start_link/0, identity_fun/1]).
start_link() ->
ThrottleConfig = [
{hourly_limit, 3600}, %% (default)
{daily_limit , 86400}, %% (default)
{identity_fun, fun my_elli_stuff:identity_fun/1}
],
Config = [
{mods, [
{elli_throttle, ThrottleConfig},
{elli_example_callback, []}
]}
],
elli:start_link([{callback, elli_middleware},
{callback_args, Config}]).
identity_fun(Req) -> elli_request:peer(Req). %% (default)
