Current behaviour

In earlier versions (tested with 1.4.7) it was possible to change properties inside the given query options. This is not possible anymore, the reference to the query object get lost.

Steps to reproduce (if the current behaviour is a bug)

var queryObj = { userOldSessionId:'none', userReconnecting:0 };
var socket = io('https://myurl/namespace', { query : queryObj});

// change query options on connect
socket.on('connect', function(){
    queryObj.userOldSessionId =;
    queryObj.userReconnecting = 1;

With this example it was possible earlier to detect reconnection server side and restore settings for this client on successful reconnection. This is not possible anymore, in inspector you will always see queries with the 'old' query options.
