# 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. |
