Compatibility

Only modern browsers are supported (IE11, latest Edge, latest Chrome, latest Firefox, latest Safari)

Requirements

A reasonably fast web server. PHP is optional but recommended (see doc.md for details)
Some way to generate garbage data (PHP script included, see doc.md for other solutions)
Your server must accept large POST requests (up to 20 Megabytes), otherwise the upload test will fail
It's also better if your server does not use compression, but it's not mandatory

How to use
