hAxe has Apache httpd modules and can compile to PHP code. These are 2 options I know to make a web application that runs on the server. You can start a http server with nekotools, but this is supposed to be used for development only.
Are there any more options?
I can always use the NekoVM from within a C or C++ program, running a web server or interfacing to FastCGI. Or compile to C++, using a FastCGI or web server library. But I want to hear about solutions that are actually used.
I have a VPS with nginx, so no mod_neko or mod_tora. PHP isn't a problem, but I'd rather wouldn't use it (for irrational reasons).
