Redirect Port 80 To 443 Nginx
What Is Port 80 And What Is It Used For?
Port 80 is a standard port for HTTP communication from the Internet to web servers. The Hypertext Transfer Protocol (HTTP) is the primary protocol used for communication between web browsers and websites. It’s the most popular protocol for sending data, such as web pages, between a web server and a web browser. This port is commonly used by web-based applications, including the HTTP protocol, which is the basis for the World Wide Web.
When a computer or device is connected to the internet, it may use port 80 as a default port to connect to web servers. This allows the computer or device to access and use a website without needing additional configuration. For example, when you type in a web address on your computer, you are using port 80 to connect to the corresponding web server.
What Is Port 443 And What Is It Used For?
Port 443 is a standard port for HTTPS communication from the Internet to web servers. Hypertext Transfer Protocol Secure (HTTPS) is a variant of the standard internet protocol HTTP which has been secured through the use of Secure Sockets Layer (SSL) and Transport Layer Security (TLS). It is the most popular protocol for secure data transfer, as it provides encryption for the data being transmitted.
Secure communication over the Internet requires the use of port 443. It is used to protect any data sent from a browser to a web server, such as browsing history, login credentials, email, payment information, and other sensitive data.
As a result, most websites use port 443 to automatically redirect visitors who arrive on port 80. This ensures the data being sent between the browser and web server is encrypted and secure. This is especially important for websites that process sensitive data, such as online banking and shopping websites.
