Hi Abimaran,
I am not sure what they mean exactly, but maybe they refer to the following difference.
Consider a
jsp like this:
and a simular jsp with calling the get method:
And a
Servlet (with a correct mapping) which just forwards (from the doGet() and the doPost() method) to another jsp where it shows the text fields
If you now refresh the page which was made after a doGet() it just refreshes, but if you refresh the page after a doPost(), the browser will ask you if you want to
re-submit your previous data (you can't
re-read it)
Regards,
Frits
