How to prevent Gunicorn from returning a 'Server' http header?

Question

I would like to mask the version or remove the header altogether.

Answer 1

Easiest way -

For newer releases(20.0.4), create file gunicorn.conf.py with below contents in the directory from where you will run the gunicorn command -

import gunicorn
gunicorn.SERVER_SOFTWARE = 'My WebServer'
