API Platform - Changing max_age config value doesn't change the max-age request value

I have an application with API Platform and an other which consume my API.

I want to change the max-age value but when I change the value in the config, it doesn't change the value when I send a request...

Here is my config:

api_platform:
  ...
  http_cache:
    max_age: 600
  ...

And here is my request and response headers: request and response headers

Tell me what I'm doing wrong.

Solution

  • The RFC discusses max-age here: Header Field Definitions
    Also this page can help you a lot : Hypertext Transfer Protocol

    The possible max-age value is dependent on browser/version and any proxy in the way.

    It makes sense to apply to cache-control too in the absence of any explicit standards guidance.

    It's as long as you should generally need anyway and picking any arbitrarily longer value could break some user-agents.
