Hey Larry, ever wondered why my server feels like it’s stuck in a traffic jam while your site pops up in milliseconds? Let’s dig into caching and see if we can turn my code into a racehorse.

Sounds like a plan. First up, let’s make sure you’re not hammering the same files through the disk every request. Add a proper cache key, leverage ETag, maybe even a simple reverse proxy in front of the app. I’ll walk you through the config. Ready?

Sure, here’s a minimal yet effective snippet you can drop into your nginx.conf. ``` http { # Cache static assets for a week map $uri $static_cache { ~*\. (css|js|png|jpg|jpeg|gif|svg)$ 1; default 0; } server { listen 80; server_name yourdomain.com; # Static files location ~* \.(css|js|png|jpg|jpeg|gif|svg)$ { expires 7d; add_header Cache-Control "public, must-revalidate, proxy-revalidate"; try_files $uri $uri/ =404; } # API or dynamic content location / { proxy_pass http://127.0.0.1:3000; # your backend proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; # short caching for 5 seconds to smooth load spikes add_header Cache-Control "private, max-age=5"; } # Logging – keep it concise access_log /var/log/nginx/access.log combined buffer=32k flush=1m; error_log /var/log/nginx/error.log warn; } } ``` A few pointers: - The `map` directive decides whether to apply long‐term cache based on file extension. - `expires 7d` tells browsers to keep those files for a week. - For dynamic content, a 5‑second “private” cache keeps the load light while still protecting data. - Keep the log buffers reasonable so you don’t get a flood of entries during a spike. Give that a try, then let me know how the traffic jam feels. If you see any hiccups, we can tweak the timeouts or the `proxy_cache` settings. Happy coding!
