doPost and doGet methods differences

[Ernesto Elias-Nieland]

Hi!
The difference is that in a POST request the request parameters are sent inside the http header. In a GET request the request parameter are added to the end of the url. For example:
www.javaranch.com?parameter=aValue

Ummm, I think with a POST, the HTML form parameters are sent in the HTTP body, not the header.

But you're asking about doGet and doPost, not GET and POST. The only difference is that one is called as result of a GET, the other as result of a POST, which the javadocs of those methods probably already told you, so this isn't very helpful. Could you elaborate a bit more on what you'd like to know?

Well, basically doPost is invoked by the Servlet's service method if it
finds that the method used in the form to submit the request is "POST".
The doGet is invoked if the request is submitted using the "GET" method.

Although both method in your servlet (doPost and doGet) can invoke common
private method to process your request and response object, one basic
difference is how the parameters are transmitted to the server (discrete or
not, etc).

Instance where doPost would be invoked in the service method:

<form action="/servlets/AnyServlet" method="POST">
...
</form>

Likewise, when you use POST, form parameters are contained in the "body"
of the HTTP message request, and not in the HTTP message header. This
makes the values you submit a bit more secure that using GET method because
they are not shown as part of the URL.

Cheers!

Please try to be more specific in your question. Especially because as you phrased google could have answered it in about 3 clicks.

The kind of http request that triggers the servlet service.
