By default, port 80 is open to HTTP (Hypertext Transfer Protocol). When users browse the web, they enter the address in the address bar of the browser. Input method: www.iis7.com:80 website followed by port number. Because the default WWW service is port 80, which is unlucky, just enter www.iis7.com directly.
Note: The default port number can be changed.
Port 80 and port 8080 are two different ports. Port 80 is open to HTTP (Hypertext Transfer Protocol), which is the most commonly used protocol for surfing the Internet and is mainly used for transmitting information on the World Wide Web. You can access the website by adding ":80" to the HTTP address (commonly known as "URL"). Because the default port number of the web browsing service is 80, you only need to enter the URL instead of ":80". Port 8080, like port 80, is used for WWW proxy service and can realize web browsing. When visiting a website or using a proxy server, the port number ":8080" is often added.
In addition, after installing ApacheTomcatwebserver, the default service port is 8080.
