In this section, we will differentiate the GET and POST method of servlet.
Java Servlet : Difference between GET and POST
In this section, we will differentiate the GET and POST method of
GET - It is HTTP method, asks to get thing at the requested
POST - It is HTTP method, asks the server to accept the body
info attached to the request, and give it to the thing at the requested URL. It
is like GET with extra info sent with the request.
- Although both GET and POST can send parameters but POST has a body. With
GET, the parameter data is limited to 255 character only what you can stuff
into the Request line. In POST, there is no such length limitation because
it works as a part of the body of the HTTP request and there is no size
limit for the body of an HTTP request/response.
- When we use GET, you can see the parameter data in the browser's
input bar, right after the actual URL, which is separated by a "?". It is
not a secure way to send request. POST request is encapsulated in the body
of the HTTP request So you can use POST in such case because POST method
- If we talk about the performance then we find that the GET request is
faster than POST request because GET request creation is simpler and it also
save time which is spent in encapsulation of POST request. The maximum
length limitation gives a better optimization of GET implementation.
- GET request holds only text data as it is sent through URL string and we
know URL can be text-only. In POST request there is no restriction so you
can carry both text as well as binary data.
- GET is idempotent that is it can be executed more than once without any
bad side effects. It is used for getting things,and it don't change anything
on the server. POST is not idempotent, the data submitted in the body of the
POST might be bounded for the transaction that can't be reversed.
- POST is not default so if you want to use POST specify in your form
method="POST". HTTP GET request is default .
