Rest API - Caching Strategies

Why might a server choose to ignore the If-Modified-Since header and always send a full response?

ABecause the client did not send an ETag header.

BBecause the resource changes too frequently or modification time is unreliable.

CBecause the server does not support HTTP/1.1.

DBecause the client requested a 304 status explicitly.

Step-by-Step Solution

Solution:

Step 1: Consider reasons to ignore If-Modified-Since
If resource changes very often or modification timestamps are not accurate, conditional requests may be unreliable.
Step 2: Understand server behavior
In such cases, server may always send full response to ensure client has latest data.
Final Answer:
Because the resource changes too frequently or modification time is unreliable. -> Option B
Quick Check:
Unreliable mod time disables conditional GET [OK]

Quick Trick: Ignore If-Modified-Since if mod time unreliable [OK]
