check headers

Сheck the headers in the request

Oh, I understand you. May be implement tagging logs in logger methods?
For example:
```javascript
exports.log = log;
exports.warn = warn;

function _log(){
    if (stealthMode) {
        return;
    }
    console.log(Array.prototype.slice.call(arguments).join(' '));
}

function log(){
    [].unshift.call(arguments,'[LOG]'.white);
    _log.apply(this,arguments);
}

function warn(){
    [].unshift.call(arguments,'[WARN]'.red);
    _log.apply(this,arguments);
}

```
