class PTHTTPPOSTRequest

extends PTHTTPRequest

Object wrapper for "in-place" client-server POST operations. Invoking a PTHTTPPOSTRequest will cause a background HTTP request to be sent to the server without reloading the contents of the browser. PTHTTPPOSTRequests can be set to automatically refresh the inner HTML of an element on the page, or to have the HTTP response that they generate be handled by a JavaScript function. All the form input values (with the exception of file inputs) will be transmitted in the PTHTTPPOSTRequest.

Usage:	
 	// refresh the content of an element
 	var myform = document.forms[0];
	var request = new PTHTTPPOSTRequest(myform.action, myform, document.getElementById('refresh-elem-id'));
	request.setRequestHeader('my-custom-header', 'headervalue');	
	request.invoke();
 
 OR
 	// invoke a response handling function
 	var myform = document.forms[0];
	function handleResponse(resp) { alert(resp.responseText); }	
	var request = new PTHTTPPOSTRequest(myform.action, myform, handleResponse);
	request.invoke();
