nginx - the meaning of middleware spawn-fcgi

Question

I built a webpy and nginx environment and used spawn-fcgi. I don’t understand what the role of spawn is? Middleware as buffer? After looking at the spawn source code, it is just an exec job. Why not communicate directly with webpy and nginx?

Please indicate

Answer 1

spawn-fcgi feels like forking out multiple processes, which can also be replaced by uwsgi. Webpy also supports native fastcgi support, but it seems that it can only be a single process
