Description
Design, implement, and review rate limiting and abuse throttling — algorithms (fixed window, sliding window, token bucket, GCRA), choosing keys (user ID, API key, IP with IPv6 prefix grouping, trusted proxy headers), shared storage for serverless (Redis/Upstash, Postgres) vs in-memory, framework implementations (Next.js route handlers/Server Actions/proxy, ASP.NET Core rate limiter, Supabase, edge/WAF rules), cost-based limits for LLM/email/SMS endpoints, login and OTP protection without lockout DoS, 429 responses with Retry-After, and fail-open vs fail-closed decisions. Use whenever the user adds rate limits, protects auth/signup/reset/OTP/search/AI endpoints, sees abuse, scraping, or runaway costs, or reviews throttling code.
