346850 - for Ajax, XMLHttpRequest can only send/receive a maximum of 4096 size

Status: RESOLVED DUPLICATE of bug 194231

(Firefox :: General, defect)

Description

[atif]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.5) Gecko/20060719 Firefox/1.5.0.5
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.5) Gecko/20060719 Firefox/1.5.0.5

I am trying to use simple XMLHttpRequest object to send/receive for Ajax implementation. However, it allows the maximum of 4096 data size on mozilla firefox. I tried the same code on Internet Explorer and it can send/receive more than 4096 data size.

here is a piece of the code I am using:
--------------------------------
//the following two functions are helper infrastructure to 
//craete a XMLHTTPRequest and register a listner callback function

function newXMLHttpRequest() {
	var xmlreq = false;
	if (window.XMLHttpRequest) {
		xmlreq = new XMLHttpRequest();
	} else if (window.ActiveXObject) {
    		// Try ActiveX
		try { 
			xmlreq = new ActiveXObject("Msxml2.XMLHTTP");
		} catch (e1) { 
			// first method failed 
			try {
				xmlreq = new ActiveXObject("Microsoft.XMLHTTP");
			} catch (e2) {
				 // both methods failed 
			} 
		}
 	}
   	return xmlreq;
} 

function getReadyStateHandler(req, responseXmlHandler) {
	return function () {
	if (req.readyState == 4) {
		if (req.status == 200) {
        		responseXmlHandler(req.responseXML);
		} else {
				alert("Ajax error");			
      		}
    	}
 	}
}


Reproducible: Always

Steps to Reproduce:
1.create a simple AJAX implementation using XMLHttpRequest object.
2.send/receive data using responseXmlHandler.
3.only 4096 bytes of data will be allowed

Actual Results:  
All data after 4096 characters are not received or sent using this Ajax support.
The same code works fine on IE.

Expected Results:  
Mozilla can also send/receive more than 4096 bytes of data

Dupe of/related to bug 194231?

responseXML was using DOM, and one of the DOM Nodes was required to be more than 4096 characters, which did not work. 
>> responseXmlHandler(req.responseXML);

However, it worked fine when responseText was used instead.
