What Is doPost

The doPost() method is called by the server (via the service method) to allow a servlet to handle a POST request. Generally, we use the doPost() method for sending information to the server like HTML form data.

Why doPost method is preferred over doGet method in PHP?

You should use doGet() when you want to intercept on HTTP GET requests. You should use doPost() when you want to intercept on HTTP POST requests. That’s all. Do not port the one to the other or vice versa (such as in Netbeans’ unfortunate auto-generated processRequest() method).

WHO calls doGet () and doPost () method?

If the HTTP Method is a GET, the service() method calls doGet(). If the HTTP request Method is a POST, the service() method calls doPost().
