Posted more as a curiosity - I’d rather see something like Chicken Scheme embedded in Nginx (similarly to OpenResty platform)
We thought that the one application you almost always run privileged in some way and processes all your secure traffic needed to have extra attack vectors so we put a JVM in it.
I think clojure is awesome, but the idea that it has a place inside nginx is a stretch for me.
Maybe this is really awesome, and everything works beautifully, but the reason openresty (the obvious inspiration) works as well as it does is simply that lua was designed from the start to be embedded.
Not to mention the stock lua interpreter implementation is something like 32kb, and a lot of work is being done by magicians (see luaJIT) to make lua a serious choice in nginx.
