Deletes all your cached URLs in prerender

_README.md

You can run this by doing the following:

1. Log into https://prerender.io
2. Open the developer console on the prerender site
3. Copy the code in this gist and paste it into your console
4. Hit enter!

Some notes:

• This script takes a while, Prerender is not very performant! So if you have a lot of cached URLs, be patient.
• I recommend opening the network tab of your developer console, and making sure that all the requests to /cached-pages and remove-cached-urls are returning 200 OK responses. If they're returning any response with status 400+ it's likely this script isn't working.
• This may stop working at any time if Prerender changes their API or API usage policies ever.
