by Danila Vershinin, April 29, 2026
We rebuilt nginx-mod with Cloudflare’s 2015 dynamic TLS records patch and benchmarked it in a controlled rig with random interleave, CPU pinning, and 200 cold connections per condition. The “50% p95 TTFB win” we expected collapsed under noise control. Here are the honest numbers and what to do instead.

by Danila Vershinin, April 22, 2026
NGINX Plus has slow_start to ramp traffic to freshly-live upstream servers from zero to full weight. Open-source NGINX has the struct field but never wired the scheduler. NGINX-MOD ships the missing scheduler logic and this article proves it with runtime measurements from a Rocky Linux VM.

by Danila Vershinin, April 5, 2026
Learn how to automatically convert and serve WebP and AVIF images in NGINX using the ngx_immerse filter module. This module transparently intercepts image responses from any source – static files, proxy_pass, or FastCGI – and converts them to modern formats based on browser support. No URL rewriting, no separate service, no application changes needed.

by Danila Vershinin, April 4, 2026
Learn how to extend NGINX with WebAssembly using the ngx_wasm_module. Write custom filters in Rust, Go, or C++ using the Proxy-Wasm standard, and run them at near-native speed inside NGINX with full sandboxing — no C modules, no recompilation required.

by Danila Vershinin, April 1, 2026
Learn how to use NGINX upstream jdomain for dynamic DNS resolution in upstream blocks. The jdomain module re-resolves domain names on the fly without reloads — essential for cloud and container deployments on older NGINX versions before the native resolve parameter.

by Danila Vershinin, March 31, 2026
Learn how to use the NGINX upstream resolve parameter for dynamic DNS resolution. Keep upstream server IPs current without restarts, handle DNS failover gracefully, and compare native NGINX 1.28+ support with the upstream-dynamic module, Angie, and NGINX Plus.

by Danila Vershinin, March 29, 2026
Learn how to use the NGINX unzstd module for transparent Zstandard decompression. Adopt Zstd compression server-side while maintaining compatibility with clients that do not yet support it — the same pattern as the built-in gunzip module, but for Zstd.
