Show HN: A very simple http “proxy” on runkit

What I'm interested in, is how can they run this stuff? How is it cost effective for them? How is it safe? Runkit is basically free serverless node. It's pretty amazing.

For those interested, the code is here: https://runkit.com/dosyago-coder-0/proxy

It does the simplest possible:

- prepends the URL form to the proxied html page

- prepends a <base> element with the proxied page's uri ( to ensure relative links point to the source and not the proxy )

- prepends a script which captures clicks on anchor links and instead of allowing the navigation to proceed submits the URL ( via the prepended form ) back to the endpoint

Also, for the sake of a technical challenge, I don't know how to get it to work on Amazon.com -- what happens is after the first load, any links clicked seem to break out of the proxy. Anyone who can work out why it doesn't work, please tell me!

edit: oops, seems as if the HN 'glance' of death ( not hug, this has only been on for 20 minutes ) kills it intermittently, and that runkit has a quota that is sometimes exceeded!
