Back in the day, Cloudflare's WAF was based on OpenResty, so the high-performance Lua-programmability at the edge (which is noted in this blog entry) was probably a factor. Quick research shows HAProxy added Lua support in 2015, which is a bit later than their use of OpenResty.

Yeah, I know, I wrote that WAF.

This exchange is almost as enjoyable as that "famous" thread about someone's math prowess (anyone have that link?)

Haha, thank you.

Haha, I missed that you had an intermediate comment -- thanks for all you+Cloudflare did for LuaJIT too :)

LuaJIT is a cool thing. Helped us a lot. But not everything remains the right thing forever.
