DRY the request part
s/service/response
Send 204 for favicon.ico requests
Use SETEX command
Fetch gzipped pages and log its duration time
Handle uncaught exceptions for winston papertrail
Pass status code as argument to jsonp method too
Extract out the dom parsing stuff into a module
Asyncify hndom and pass error objects too
Add missing `cleanContent` function
Fix caching the wrong data
toString for the errors
Fixing the syntax, all `var`s
