I’m running into a problem where my http(s) requests are getting mangled before they reach my application. Any help would be greatly appreciated.

Your request to the router is using `Transfer-Encoding: chunked` but the request between the router and your container is not. Do you need this transfer-encoding preserved?

Aha, you’re right… Ruby web servers seem to have a very hard time dealing with it.

In case anyone stumbles onto this, [this gist](https://gist.github.com/thom-nic/8b586749d3b88bef8c59) works for me.

Thanks!
