Rest API - Caching Strategies

Consider this REST API server with caching enabled. What will be the output of the following sequence?

1. Client requests resource A (not cached)
2. Server processes and caches response for A
3. Client requests resource A again
4. Server returns cached response

What happens at step 4?

AServer returns the cached response instantly without processing

BServer processes resource A again and returns new response

CServer returns an error because cache is empty

DServer delays response to check for updates

Step-by-Step Solution

Solution:

Step 1: Understand caching steps
At first request, server processes and caches the response. On the second request, the cached response is available.
Step 2: Behavior at repeated request
Server returns the cached response immediately without reprocessing, speeding up response time.
Final Answer:
Server returns the cached response instantly without processing -> Option A
Quick Check:
Cached response served = A [OK]

Quick Trick: Cached data skips processing on repeat requests [OK]

Common Mistakes:

MISTAKES

Thinking server recalculates every time
Assuming cache is empty on second request
Believing server delays to check updates
