The POST method of the HTTP protocol is used to submit data from a client (such as a web browser) to a server. When a user submits a form or uploads a file, the data is sent as part of an HTTP request using the POST method. The process follows the following steps:
1. The client sends a request to the server using the POST method, including the URL of the server and the data to be submitted.
1. The server responds to the request with a status code (usually 200 OK) and any data that may be included in the response.
1. The data is then processed by the server and may be stored in a database or used to perform some other action.
1. The server may respond to the client with a new Web page, updated data, or some other form of feedback.
1. The client can then display the new Web page or updated data to the user.
The POST method differs from the GET method (which is used to retrieve data from the server) in that it is used to send data to the server. Additionally, while the GET method appends data to the URL, the POST method sends data as a separate entity in the request.
