# 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.

I was tired of Chrome eating all my laptop resources so I decided to put some limit to it with cgroup.

As I was using Ubuntu 12.04 with support for cgroup, I installed the package cgroup-bin and add the following group to the file /etc/cgconfig.conf:

group browsers {
    cpu {
#       Set the relative share of CPU resources equal to 25%
        cpu.shares = "256";
 }
