Modern alternative to CGI/FastCGI

[Viete]

Thanks Thomas, that helps as I didn't know other frameworks use this idea. 

How would I go about also keeping a communication channel open for
continuous data flow (for example, if I'd like to have nginx returning a
stream of jpeg files (MJPEG) after the proxy_pass all)?

Thank you!
