Secure Socket Tunneling Protocol is recognized for its Windows integration and the ability to create a secure VPN connection. The use of SSL encapsulation over TCP port 443 is a primary advantage, enabling SSTP to pass through firewalls and proxy servers that would typically block VPN traffic. Thi...
Port 443: Standard port for HTTPS traffic, used by HTTPS proxy servers for secure, encrypted connections. Port 8080: An alternative port for HTTP traffic, frequently used by HTTP proxies. Port 1080: Typically used by SOCKS proxy servers, which can handle various types of traffic, including web...

HTTP typically uses port 80 as its default—this was established early in the development of the web for sending and receiving content. HTTPS uses port 443. Which is reserved for encrypted traffic. URL Format A uniform resource locator (URL) serves as the address for locating resources on the...
The primary purpose of SSL is to provide a secure transport-layer connection between two endpoints, the server and the client. This connection is typically between a website server and the client’s browser, or a mail server and the client’s email application, such as Outlook. ...
