macOS Safari caching response, while headers specify no caching

Question

A response from the server to a GET request has the following headers:

HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8
Pragma: no-cache
Date: T         


        

Answer 1

I've had a similar problem (see Safari Caching GET request even with disabled cache). Adding Vary: * forced Safari to stop caching. Nothing else worked, including Vary: Cookie even though cookies changed between requests.
