You probably have it many times and it is one of the HTTP status messages. HTTP status messages are a means of communication between browser and server. The HTTP status messages have been categorized into five categories, they are:
- Informational,
- Successful,
- Redirection,
- Client Error, and
- Server Error
The HTTP information status message means that the request made by the browser to the server has been received and is in a continuing process. As this status message is not a final response, therefore it cannot be observed. The HTTP information status message category is described here with its derivatives as well.
HTTP information status message
The HTTP information status message is classified into further four message types:
- 100 continue,
- 101 switching protocol,
- 102 processing, and
- 103 early hints.
The first digit of each status message code represents its class. The information status messages are referred to as 1xx informational status messages thus all the derivatives of information status messages have code “1xx” with their names.
100 continue
The 100 continue status message refers to the initial part of the request sent by the browser to the server. The client must proceed with the body of the request, once the server has received the request.
101 switching protocol
This information status message refers to the request made by the client to the server which asks for changing the application protocol. In response, the application protocol would be changed by the server.
102 Processing
The 102 processing shows that the request has been accepted by the server but the request has not yet been completed thus no response would be available.
103 Early Hints
As the name shows, this status message allows the client to preload the resources, and in the meantime, the server prepares a response.
Conclusion
The HTTP information status messages keep on tracking the sent request and the behavior of the server to that request. The HTTP information status messages are divided into three categories and each category tells the status of the request and the relevant response of the server. The 100 Continue refers to the initial part of the request made by the client, the 101 Switching Protocol represents that the client wants to change the application protocol, 102 Processing means the server has accepted the request whereas the 103 Early Hints tell the client that the server is preparing a response.
