I want to get the action and the parameter so that the it can be submitted to an alternate location ,what i am tryin to do is try writing a proxy website.

Can't you just concatenate the form's action with a serialization of the form's data, e.g.:

$('form').submit(function() {
  alert($(this).attr("action") + $(this).serialize());
  return false;
});
