Context: Hi Guys , I ' ve built an awsome AJAX custom http handler which through reflection automatically prototypes classes to javascript objects and creates javascript methods which match the server side method taged with my custom attributes . The model allows you to pass object from both server to client and client to server . It handles all the serialisation and has cut my development time of an AJAX heavy web application in half . The only thing left to do in polishing the model is to finish error handling .
Question: Where might the custom http handler be used most often ?
Options: 
- It would be used at work to allow items to be sent back and forth between you and the customer .
 - It handles all the serialisation and has doubled my development time but you can still use it at home .
 - It would mostly be used while polishing models and cutting applications use in half , saving money .
 - It would be used to prototype models and turn html into javascript in order to save time .
