NodeJS - post data is cached in the request body

Question

I have two node servers where node server2(port 3001) receives requests from node server1(running on port 3000).

When i bind data in server1 and make post call to server2 , server2 always caches the old data maintained in previous call.

   For ex : Old Post data is     { emailid : 'xxxx',
                          name : 'XXXX',
                          records : [0,1,2,3,4]
                          } 

      If Next POST data from server1 is       { emailid : 'xxxx',
                                            name : 'XXXX',
                                            records : [5,6]
                                          } 
      Then Server2 recieves these data as      { emailid : 'xxxx',
                                            name : 'XXXX',
                                            records : [5,6,2,3,4]
                                          } 

     I dont want the old records 2,3,4 in req.body.records array .. but it is cached. 

     Could you please help me how to remove the caching of the old data in request body container.


    Please look at my server1 code where i make REST calls using node request module:

Server1 comfiguaraton -

app.configure(function() {
    // The cookieParser should be above session
     app.use(express.cookieParser());
    app.use(express.session({secret:'ayer'}));

    // Request body parsing middleware should be above methodOverride
    app.use(express.urlencoded());
    app.use(express.json());
 //      app.use(expressValidator());
    app.use(express.methodOverride());

    // Routes should be at the last
    app.use(app.router);

// Setting the fav icon and static folder
//app.use(express.favicon());
app.use(express.favicon(__dirname + '/public/favicon.ico'));
//app.use('/', express.static(config.root + '/public'));

 });

Method that make rest API call to server2 exports.docleansematch = function(req,res,sessionStore){

/*setting up user verification request options*/
var Options = {
    uri: 'http:localhost:3001/docleansematch',
    method: 'POST',
    json:true,
    proxy: config.app.proxy, // calling to internal server
    headers: {'Content-Type':'application/x-www-form-urlencoded'
              },
    form : req.body

};
request.post(Options,function(err,extResponse,extResponseBody)
{
    var data = {};
    if(err)
    {
        log.error('Error in App layer : ',err);
        data.status = 2;
    }
    else
    {
        data.status = extResponseBody.status;

    }
    res.jsonp(data);

});

};

Server2 Method that receives the request data:

app.post('/docleansematch',function(req,res){


    log.info('Cached Number of records - '+ req.body.records.length);


    res.json({status:3}); 
}
