With the help of javascript i have created set Cookie() function. In the below code I have store all the values in the single cookie. By using this function many cookies will store at a time.

<script type="text/javascript">
  var today = new Date();
  var expiry = new Date(today.getTime() + 30 * 24 * 3600 * 1000); 

  function setCookie(name, value)
  {
    document.cookie=name + "=" + escape(value) + "; path=/; expires=" + expiry.toGMTString();
  }
</script>

The setCookie function is called by the form using the following function:-

<script type="text/javascript">

  function storeValues(form)  
  {
    setCookie("field1", form.field1.value);
    setCookie("field2", form.field2.value);
    setCookie("field3", form.field3.value);
    setCookie("field4", form.field4.value);
    return true;
  }

</script>
