Explanation

In an explicit proxy configuration, client browsers are manually configured (or pushed via policy) to direct their HTTP/HTTPS requests to a specific proxy server address and port. Port 8080 is the industry-standard and most commonly used port for this purpose. Port 80 is the standard HTTP port for direct web traffic (not proxy traffic). Port 443 is standard HTTPS. Port 8443 is sometimes used for HTTPS proxy but is far less common than 8080. Palo Alto's explicit proxy feature also defaults to listening on port 8080.
