What is Rate Limiting?
Rate limiting is a technique used to control the number of requests a client can make to a server within a given time period. This helps prevent abuse, protects against brute-force attacks, and ensures server stability under heavy load.
Common Rate Limiting Strategies:
- Fixed Window: Limits the number of requests per fixed time interval.
- Sliding Window: Tracks request rates dynamically to smooth traffic spikes.
- Token Bucket: Allows bursts of traffic while enforcing an average limit over time.
Rate limiting is widely used in APIs, login forms, and web applications to prevent abuse, reduce server load, and maintain service reliability.
