Common Mistakes

Using 'public' which allows shared caches.

Using 'no-store' which disables caching.

The private directive allows caching only in private caches like browsers, not shared caches.

4fill in blank

hard

Fill both blanks to set Cache-Control to cache for 30 minutes and require revalidation.

Rest API

response.headers['Cache-Control'] = '[1], [2]'

Drag options to blanks, or click blank then click option'

Amax-age=1800

Bno-cache

Cmust-revalidate

Dno-store

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'no-cache' which disables caching.

Using 'no-store' which disables caching completely.

max-age=1800 caches for 1800 seconds (30 minutes), and must-revalidate forces revalidation after expiration.

5fill in blank

hard

Fill all three blanks to set Cache-Control to no-store, no-cache, and private.

Rest API

response.headers['Cache-Control'] = '[1], [2], [3]'

Drag options to blanks, or click blank then click option'

Amax-age=0

Bno-store

Cno-cache

Dprivate

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'max-age=0' which is less strict than 'no-store'.

Mixing 'public' instead of 'private'.

no-store disables storage, no-cache requires revalidation, and private limits caching to private caches.
