Securing Your Rest API Application With Python

Throttling manages high request volumes by slowing down requests instead of blocking them. Unlike rate limiting, which rejects excess requests, throttling adds delays when thresholds are exceeded. This keeps your API responsive and stable during traffic spikes.

Modern web apps often need to fetch resources from different domains. CORS defines how servers declare which origins can make requests. By default, browsers block cross-origin requests, so you'll configure your FastAPI server to respond with the necessary headers.
