Nginx vs Apache for Reverse Proxy, PHP, and Static File Serving

Nginx uses an event-driven worker model suited to many concurrent keep-alive connections with modest memory. Apache’s process/thread MPMs shine when .htaccess per-directory overrides are mandatory for shared hosting.

Modern PHP deployments typically use php-fpm behind either web server; the choice is often operational familiarity and config style, not raw throughput alone.

Concurrency models

C10K-class workloads historically favored nginx’s async model; Apache event MPM narrowed the gap but tuning differs.

Slow clients can tie up Apache worker threads; nginx buffers upstream more gracefully in reverse proxy mode—still monitor upstream timeouts.

.htaccess and shared hosting

AllowOverride enables per-directory rules without server reload—great for multi-tenant cheap hosting, expensive on high-traffic sites due to per-request directory scans.

If you control the full vhost, prefer explicit config includes over deep .htaccess chains.

Reverse proxy patterns

  • Terminate TLS at nginx, HTTP/2 to clients, HTTP/1.1 or HTTP/2 to upstream app servers.
  • Set `X-Forwarded-*` headers carefully; apps must trust proxies only from known IPs.
  • WebSocket upgrades need explicit proxy headers in both servers.

Static files and caching headers

Serve immutable assets with long `Cache-Control: max-age` and fingerprinted filenames; HTML stays short TTL.

Compare `sendfile` and `aio` behavior on your filesystem when benchmarking static throughput.

Frequently asked questions

Apache obsolete?
No—still common where .htaccess and module ecosystems matter; nginx is dominant at CDNs and high-concurrency proxies.
Both together?
Yes: nginx on edge as TLS terminator and cache, Apache/mod_php only if legacy demands—document the hop.
