HTTP protocol detailed (URL explanation)

The URL (uniform Resource Locator) address is used to describe a resource on a network, and the basic format is as follows schema://host[:p ort#]/path/.../[;url-params][?query-string][# Anchor

scheme specifies protocols for low-level use (for example: HTTP, HTTPS, FTP)

The IP address or domain name of the host HTTP server

The default port for the port# HTTP server is 80, which can be omitted from the lower number. If you use a different port, you must indicate, for example, http://www.cnblogs.com:8080/

HTTP indicates that a network resource is to be located through the HTTP protocol; Host represents a legitimate Internet host domain name or IP address; port specifies a port number, NULL, and the default port 80;abs_path specifies the URI of the requested resource; If Abs_ is not given in the URL Path, then when it is the request URI, it must be given in the form of "/", which is usually done automatically by the working browser.
