TriremeServlet recieve big data error.

[sunchey11]

I use triremeServlet to embed trireme to a web project.
But when I transfer large data, I can't receive data correctly. Some code below:
server.js

var http = require('http');

function handleRequest(req, resp) {
    req.setEncoding('utf-8');
    var postData = "";
    var count = 0;
    req.addListener("data", function(postDataChunk) {
        count++;
        console.log("%s times",count);
        console.log(postDataChunk);
        postData += postDataChunk;
    });
}

var server = http.createServer(handleRequest);
var port = 8080;
server.listen(port, function() {
    console.log('Listening on %d', port);
});

html page code

<script type="text/javascript">

    var url = "MyTriremeServlet";


    var longContent = "";
    for(var i = 0;i < 1000;i++){
        longContent += i + "-";
    }
    var param = {name:"longContent","content":longContent};
    $.post(url,param);

</script>

</web-app>

When I run the project, only last piece of data can be received, the other data is same to the last piece of data.

Can you include the output from the server (it seems to do a lot of
console.log)? I'm not sure exactly what is being output.

Sorry I didn't get to this -- the servlet code was trying to re-use a byte array and re-write it before the Node code was done reading it. I reproduced the problem and fixed it now.
