Rest API - Rate Limiting and Throttling

How can you combine the Retry-After header with caching headers to optimize client retries?

ASet Cache-Control no-cache to ignore Retry-After

BSet Cache-Control max-age to zero to force immediate retry

CUse Retry-After only without caching headers

DSet Cache-Control max-age equal to Retry-After seconds

Step-by-Step Solution

Solution:

Step 1: Understand caching and Retry-After interaction
Cache-Control max-age defines how long a response is fresh; Retry-After tells when to retry.
Step 2: Align caching with Retry-After
Setting max-age equal to Retry-After seconds helps clients cache the response and avoid retrying too soon.
Final Answer:
Set Cache-Control max-age equal to Retry-After seconds -> Option D
Quick Check:
Cache max-age = Retry-After seconds for efficient retries [OK]

Quick Trick: Match Cache-Control max-age to Retry-After seconds for smooth retries [OK]
