To understand the topic, we must first break down the encoding: : This is the hex code for a colon ( : ). 2F : This is the hex code for a forward slash ( / ). Full Decode : 3A-2F-2F-2F becomes :/// . 2F : This is the hex code for a forward slash ( / )
A proxy application receives proxy-url-file:/// from the user. The app, trying to be safe, URL-encodes the entire string. : becomes %3A . / becomes %2F . So :/// becomes %3A%2F%2F%2F . The full string becomes: proxy-url-file%3A%2F%2F%2F .
To understand the fragment, we must first decode it. The string contains 3A and 2F , which are hexadecimal byte values in (also known as URL encoding).
When coupled with proxy routing, this specific pattern is commonly deployed in two environments: 1. Automated Proxy Configurations (PAC Files)
