HTTP State code (HTTP status codes)

When we visit a webpage, the browser sends a request to the Web page's owning server. Before the browser receives the server response information and displays the Web page, the server sends a header with an HTTP status code in response to the client request.

Common HTTP Status codes:

• 404: The requested resource or webpage does not exist
• $: Request succeeded
• 301: The resource (or Web page) is permanently moved to a different URL (302 indicates a temporary move and the client should continue to use the original URL)
• : Internal server error
• : Client continues to request

　　HTTP Status Code classification:

The HTTP status code consists of three-bit decimal numbers, the first decimal number defines the type of the status code (1,2,3,4,5, respectively), so the HTTP status code is divided into 5 classes.
