i am using this code in my project

response.sendRedirect("LoginForm1.jsp?msg=Username or Password is incorrect!");

but i wan't to hide this message from url.please help me.

you gave me the response Hi Jamsiya

Instead of appending the variables in the URL, better save them in a session and retrieve the same when you need them. Here your privacy is maintained while redirecting. You can also use removeAttribute() method to delete the unwanted attributes.

,very thanks but i didn't get clearly give me one example
