you can use the html form and javascript to do this once page loads
Code:
//perform some operations and then submit
<body onLoad="document.form1.submit();">
<form method="get" name="form1" action="your url">
<input type="hidden" name="name1" value="value1">
<input type="hidden" name="name2" value="value2">
</form>
</body>
