HostLoom.RateLimiting.HttpClient

Outgoing HttpClient integration for HostLoom rate limiter profiles. The handler acquires one permit per physical HTTP attempt, supports bounded local waiting, and throws typed exceptions for local rejection or backend denial instead of manufacturing HTTP 429 responses.

builder.Services
    .AddHttpClient("catalog", client =>
        client.BaseAddress = new Uri("https://catalog.example"))
    .AddHostLoomRateLimit("catalog-api", options =>
    {
        options.MaxWait = TimeSpan.FromSeconds(2);
        options.QueueLimit = 32;
    });

Register the rate limiter after retry or hedging handlers so it sits closest to the network and charges every physical attempt. Register it before those handlers to charge only the logical request instead.

MaxWait includes store acquisition and local delay time. QueueLimit bounds callers in the wait loop for one handler pipeline; it is not a global queue and has no oldest-first or cross-instance FIFO guarantee. Both defaults are zero, which rejects immediately. A positive MaxWait requires a positive QueueLimit.

  • RateLimitExceededException reports local exhaustion and an optional RetryAfter.
  • RateLimiterUnavailableException reports a store failure when OnUnavailable is Deny.
  • Explicitly degraded admissions and ordinary responses, including a real downstream 429, proceed unchanged.
  • Handler disposal does not dispose the shared limiter.

RateLimitedHttpMessageHandler also has a public constructor for container-free composition.
