# hand-stateful

> http stateful ( cookie & session support), compatible with handover, connect/express


## Why made this?

[express-session][es], recommanded by connect/express, overwrite cookie. so, I can use cookie & session concurrently.

This module is support cookie (by [cookies][co]), and session.

Install this, then you can enjoy stateful http!
