Parsing HTTP status code 100: what does it mean?

HTTP status code 100 detailed explanation: What does it mean?

HTTP status code is a common message status indication method in Internet communication, used to identify the request status and server response status. Among them, status code 100 is one of the request status codes. Its meaning is to indicate that the server has understood the client's request and the request can continue.

In the HTTP protocol, each status code has its specific meaning and purpose. Status code 100 is an intermediate status code that is typically used when a client sends a request to the server. When the client sends a request to the server, the server will return a status code to indicate the processing status of the request.

Common uses of the 100 status code include:

1. 100 Continue: This is the most common 100 series status code, indicating that the server has received the request header and the client can Continue sending the body of the request. This status code is usually used when the client needs to send a large amount of data to confirm that the server is ready to receive data. After receiving the 100 Continue status code, the client can continue to send the body data of the request.
2. Status codes other than 100 Continue: 100 series status codes other than 100 Continue are rarely used. They are usually used in some special situations. For example, the 101 Switching Protocols status code is used to indicate that the server will switch protocols; the 102 Processing status code is used to indicate that the server is processing the request; the 103 Early Hints status code is used to indicate that the server is sending partial request results.

The use of the 100 status code is very important for communication between the client and the server. The existence of this status code can avoid deadlock situations in network communication, allowing the client and server to better exchange data. After the client sends the request, if it does not receive the 100 Continue status code, it can consider interrupting the request or resending the request.

In actual applications, developers can use the 100 status code as needed. For developers, understanding the meaning of each status code and using status codes appropriately can improve the reliability, stability and efficiency of the application.

In short, HTTP status code 100 is an intermediate status code indicating that the request can continue. Its main function is to confirm that the server has understood the client's request and is ready to receive the body data of the request. The correct use of the 100 status code can facilitate communication between the client and the server and improve the performance and stability of Internet applications.
