Hello, would it be possible to cache with nginx below 1 second ? I mean in the hundreds of milliseconds ? For example: proxy\_cache\_valid 200 301 302 500ms; Have a good day, JC – Jean-Christophe Petit VP R&D et DSI GROUPE SYSPARK The Power of Internet Engineering / La Force du Gnie Internet 606 Cathcart, Suite 510 Montreal, Quebec H3B 1K9 - CANADA T: 1 514 875 8755 C: 1 514 575 5560 F: 1 514 875 8775 ---
