Drupal Cache Max-Age
Max-age defines time-based cache validity in seconds.
When to Use
- Caching external API data with known refresh intervals
- Time-sensitive content (countdowns, live scores)
- Understanding why anonymous pages stay cached
- Debugging UNCACHEABLE responses
Critical Behavior
Page Cache ignores max-age - Only uses tags for invalidation. Dynamic Page Cache respects max-age - max-age:0 causes UNCACHEABLE. Max-age bubbles up - Minimum value wins across render tree.
