checkbox value is not sent in HTTPRequest if unchecked

There is a checkbox in my jsp page

<input type="checkbox" name="myCheck" id="myCheck">

I am submitting the form and on server side,I am trying to retrieve it using

request.getParameter("myCheck");

If I have checked the checkbox,it is coming in request as true else it is not present in request object.

My Requirement is that It should also come as false if I have not checked it. Any suggestion?

UPDATE

I am using GET method and yes it is present in the form which I am submitting.
