J2EE: SERVLET: doGet() vs. doPost()

Do you like this Article?

doGet():

protected void doGet(HttpServletRequest req, HttpServletResponse resp)throws ServletException, java.io.IOException – is a method of Class HttpServlet. It is called by the server (via the service method) to allow a servlet to handle a client's GET request.
In doGet(), the client’s request parameters are appended to the URL and sent along with header information.
doGet() is not a secured process because the request parameters are clearly visible in the URL.
Since request parameters are sent along with header information, so only a limited amount of data should be sent.

doPost():

Protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException – is a method of Class HttpServlet. It is called by the server (via the service method) to allow a servlet to handle a POST request.
In doPost(), the client’s request parameters are submitted via form.
As in doPost(), client’s request parameters are sent via form body, the parameters’ values are not visible in any where, so its safe and secure.
This method allows the client to send data of unlimited length to the Web server a single.
