Static Asset Cache Buster
If your deployments are done via version control, take advantage of this. Use commits sha #'s as a cache buster. Suggested only for smaller files where a more robust solution may not be necessary.
ruby a la sinatra view
<script src="js/main.js?<%= `git rev-parse --short HEAD` %>"></script>
php
<script src="js/main.js?<?php echo trim(shell_exec('git rev-parse --short HEAD')) ?>"></script>
