I don't understand what will be the conduct in the Apache using this config : - Pragma/Cache-Management has a similar purpose and you also give them 2 differents configs.

So how can or not it's revalidated ? https://bookmarkahref.com/story20980006/not-known-facts-about-%E4%BB%AE%E6%83%B3%E9%80%9A%E8%B2%A8%E3%82%AB%E3%82%B8%E3%83%8E
