A quick script to test 200, 404, and 500 errors on an nginx box (requires URLs that will result in 200, 404, and 500)
#!/bin/bash
#
# Author: Patrick Bailey
# License: MIT
#
# Set the percentage of 200, 404, and 500 errors you want
# Set the hourly rate you want
# Set a URL for 200, 404 and 500
#
# Then run it. it will suffle the 200, 404, and 500 urls
# (Just for testing)
