>>> urlparse("//evil.com")
ParseResult(scheme='', netloc='evil.com', path='', params='', query='', fragment='')

I see evil.com in the netloc field, ok. But Firefox doesn't use Python to parse and url, and typing //evil.com in the address bar converts the address to file:////evil.com. Not a website, but a local file.

So I don't understand the redirection part. Could you maybe write a vulnerable CGI script to demonstrate the bug?

I wrote the following HTML file to try to understand the bug, but I was only able to show the content of my local file /etc/issue:

<head>
    <META http-equiv="refresh" content="5;URL=////etc/issue">
</head>
<p><a href="////etc/issue">issue</a></p>
