Caddy 2 has an embedded scripting language that allows this. We have to flush it out some more but it's looking really good. In some of our early testing on basic workloads, we found that it's up to 2x faster than NGINX+Lua, largely because it does not require a VM. (This is a broad generalization, and we need to specifically optimize for these cases -- but this approach holds promise.)
