Frequently Asked Questions
Which strategy?
Exponential backoff with jitter beats fixed delays under load.
What counts as retryable?
Network errors, 429s, and 503s qualify — never 4xx client errors.
Max attempts?
Three to five with growing delays; more hammers struggling servers.
Is my policies uploaded anywhere when using HTTP Retry Policy Builder?
No — building runs locally in your browser, free with no signup.
What are the exact defaults per strategy?
Exponential: maxRetries 3, baseDelay 1000 ms, maxDelay 30000, jitter on, statuses 408, 429, 500, 502, 503, 504. Linear: 3 retries at fixed 1000 ms with the same 6 statuses. Circuit Breaker: failureThreshold 5, resetTimeout 60000 ms (60 s), halfOpenMaxRequests 3, statuses 500, 502, 503, 504. Diagrams print waits like 1000-2000-4000 ms with 1-decimal totals.
