I’m trying to understand proxy caching, specifically for our php scripts. How? what? when? Can anyone give me some basics? What about php scripts which serve dynamic data? Thanks ---

I suggest you read [GitHub - nginxinc/nginx-wiki: ARCHIVED -- Source for the now archived NGINX Wiki section of https://www.nginx.com · GitHub](http://wiki.nginx.org/NginxHttpProxyModule) and the mailing list archives (searched via google), then experiment in a test environment. That’s the only way you’ll really understand what’s going on and be able to apply it to your own applications. As for your PHP scripts, whether or not caching them is good or bad totally depends on your application - they should only be cached if slighly old data being served to users doesn’t break things. – RPM
