/*
A little node.js server for testing html5 ajax file uploads.

It serves up the current directory and receives uploads at /upload.

This is for use with xhr.send(file) where the entire request body is the file.
It just pauses one second between chunks so that client-side progress events
get a chance to fire. On my laptop it looks like the maximum chunk size is
around 40K, so you would still need images in the range of hundreds of kilobytes
to really be able to test it.

Get Homebrew installed on your mac if you don't already have it

Step 1:

Install highlight. "brew install highlight". (This brings down Lua and Boost as well)

These are the steps I went through to set up an SSL cert.

Purchase the cert
