Which rate limiting algorithm should I use for a high-traffic API?

The Sliding Window algorithm is generally recommended for APIs as it provides a smoother experience and prevents request bursts at the edges of time windows compared to Fixed Window.

Can I limit requests by both IP address and username?

Yes, this skill demonstrates how to use compound keys in your RateLimiter factory, allowing you to create specific limits based on a combination of client IP and user identifiers.

Does this skill help with distributed application environments?

Yes, while providing local configuration examples, it includes best practices for using Redis storage to maintain consistent rate limits across multiple server nodes.

How do I notify users when they have been rate-limited?

The skill provides patterns for returning a 429 Too Many Requests response along with standard HTTP headers like 'Retry-After' and 'X-RateLimit-Remaining' to inform clients when they can try again.

安全与测试

Implements robust request throttling and API protection for Symfony applications using advanced rate-limiting algorithms.

关于

The Symfony Rate Limiting skill provides expert guidance on implementing the Symfony RateLimiter component to protect your application from abuse and manage traffic flow. It offers domain-specific patterns for configuring sliding window, token bucket, and fixed window policies tailored for various scenarios like login throttling, API consumption tiers, and resource-heavy background tasks. By integrating this skill, developers can quickly implement secure controllers, event subscribers for global enforcement, and automated HTTP header responses (like Retry-After) to ensure high availability and fair usage of web resources.
