Nginx Image Filter with Caching for Upstream
View nginx.conf
########################################################################################################
# This config enables us to:
# - Resize
# - Rotate
# ...the resident images on an upstream server, with Nginx Server in our hand, On the fly!
# - Just by using arbitrary Query Parameters
# ...and
# - Cache the transformed image by address.
#
# Well, I got the Idea from https://stumbles.id.au/nginx-dynamic-image-resizing-with-caching.html
