Detailed explanation of HTTP status code 300 and its application in network communication

HTTP status code refers to a three-digit digital code returned by the server to the client during HTTP communication. It is used to indicate the processing and results of the current request. Among them, HTTP status code 300 represents a variety of options.

In network communications, the main application scenarios of HTTP status code 300 are in web page redirection and content selection. When a client initiates a request, the server may return multiple optional URLs as a response. At this time, the server will use a specific 300 status code to instruct the client to take further action.

Specifically, HTTP status code 300 includes the following common status codes:

1. 300 Multiple Choices: The server returns multiple optional resources, For client selection. Clients can choose appropriate resources to access according to their own needs.
2. 301 Moved Permanently: Indicates that the requested resource has been permanently moved to another URL, and the client should resend the request using the new URL.
3. 302 Found (temporary redirection): Indicates that the requested resource has been temporarily moved to another URL, and the client should resend the request using the new URL.
4. 303 See Other: Indicates that the client should use the GET method to obtain the specified resource.

Suppose that the URL of a web page is https://www.example.com, but the web page has been moved to the new URL https://www.example.com/new-page. If the client accesses the old URL, the server can return a 301 or 302 status code and redirect the client to the new URL.
