If you don't like nested callbacks, you can always flatten it with named
functions:
```js
CDN.use(config.CDN.baseUrl, cdn_next)
function cdn_next(req, res, next){
if(err) { next(); throw err; }
fs.lstat(config.base+"/cdn"+req.url, fs_lstat_next)
}
function fs_lstat_next(err,stats){
if(stats.isSymbolicLink()) {
fs.readlink(config.base+"/cdn"+req.url, fs_readlink_next)
}
}
function fs_readlink_next(err, linkstr){
// and so on
}
```
