That's most likely all cpanel php WordPress stuff that relies on .htaccess files

That chart counts nginx and openresty as separate categories. If you combine them (which I think makes more sense, since a lot of openresty's adoption must come from ingress-nginx), nginx/openresty would be at 34%.

Either way I'm happy with a wide variety of products doing the job, it avoids lock-in.

Personally I use apache as I have very few users (internal facing stuff), it has a nice simple mod_auth_openidc config which remains the same from one year to the next

I do have to recompile ws_tunnel though as I proxy a broken product I proxy which doesn't accept the correct standard for camel-capped "WebSocket" -- my "fix" script runs

sed -i 's/WebSocket/websocket/g' ./modules/proxy/mod_proxy_wstunnel.c

and recompiles

> As of June 2022 W3Tech's web server count of all web sites ranked Nginx first with 33.6%. Apache was second at 31.4% and Cloudflare Server third at 21.6%.

From the wiki.

It's interesting, it sounds like Apache is closer than I thought. I posted Netcraft's link since I've followed them for years, I'm not as familiar with W3Tech. I can't speak to which has more reliable data but W3Tech's numbers doesn't surprise me.
