# Sample Nginx config with sane caching settings for modern web development
#
# Motivation: 
# Modern web development often happens with developer tools open, e. g. the Chrome Dev Tools. 
# These tools automatically deactivate all sorts of caching for you, so you always have a fresh 
# and juicy version of your assets available.
# At some point, however, you want to show your work to testers, your boss or your client. 
# After you implemented and deployed their feedback, they reload the testing page – and report 
# the exact same issues as before! What happened? Of course, they did not have developer tools 
# open, and of course, they did not empty their caches before navigating to your site.
