class PTHTTPGETRequest

extends PTHTTPRequest

Object wrapper for "in-place" client-server GET operations. Invoking a PTHTTPGETRequest will cause a background HTTP request to be sent to the server without reloading the contents of the browser. PTHTTPGETRequests 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.

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