Configuring Nginx for API Caching to Improve Mobile Performance on Linux
Could someone explain I'm integrating two systems and I'm optimizing some code but I'm optimizing some code but I've been banging my head against this for hours. Currently developing a RESTful API that serves a mobile application, I've been diving deep into optimizing responses for improved performance. The goal is to cache certain API responses on the server side using Nginx to minimize latency for mobile users. My initial configuration attempts haven't yielded the expected results. Here’s the snippet I added to my Nginx configuration: ```nginx location /api { proxy_pass http://backend_service; proxy_cache my_cache; proxy_cache_valid 200 10m; add_header X-Cache-Status $upstream_cache_status; } ``` I set up a basic caching mechanism, but the responses don't seem to be cached as intended. I checked the response headers, and the `X-Cache-Status` always returns `MISS`. To troubleshoot, I verified that the backend service is correctly responding with a `200 OK` status and that the `Cache-Control` header isn't set to `no-store` or `no-cache`. I also tried various cache settings and modifying my backend response to include `Cache-Control: public, max-age=600`, but the caching still isn’t functioning as I anticipated. Has anyone successfully configured Nginx for caching REST API responses in a similar context? Any additional headers or settings I might be missing would be greatly appreciated. Debugging this would really help enhance the mobile experience by reducing load times. Any ideas what could be causing this? This is my first time working with Nginx stable. Thanks for any help you can provide! This issue appeared after updating to Nginx 3.9. Could this be a known issue? This is happening in both development and production on Linux. I'm coming from a different tech stack and learning Nginx. Is there a simpler solution I'm overlooking?
