        // this is the cookie value being set
        request.session_token
        // this is the raw data stored in the session, DO NOT edit this manully
        // you MUST use request.sessionSet in order to trigger the data being saved
        request.session

        // save a new session value
        request.sessionSet("my-key", "some special value");
        // get the value back from the session this is the same as request.session.my-key

app.start();
```

## Settings
```javascript
var yaps = require("yaps");
var yaps_sessions = require("yaps-sessions");

var app = new yaps.server({
    // this has to be an already initalized instance with the following methods
    // defaults to a built in `memory_store`, hint: do not use the built in store
    // it is good enough for testing, but does not provide any method of session
    // cleanup, meaning the session data for each user could potentially stay in memory
    // for EVER (until the server is restarted)
    //
    //     set: function(session_token, session_value, session_ttl)
    //          session_token: this is the session cookie value to store data for
    //          session_value: this is the raw session, e.g. {"my-key": "some session data"}
    //          session_ttl: number of seconds until this data is out of date
    //     get: function(session_token)
    //          session_token: the cookie value of the session to lookup
    //          returns: the raw session data as a js object, e.g. {"my-key": "some session data"}
    //     delete: function(session_token)
    //          session_token: this is the cookie value of the session to remove
    sessionStore: my_custom_store,

    // whether or not to regenerate a users session token on each request, default is false
    regenerateTokens: true,

    // method to use for generating user session tokens, default is uuid.v4()
    generateToken: function(){
        return "some super secret key";
    },

    // number of seconds until the session data should expire, default is 0 (keep forever)
    // the ttl is updated every time the session is set (for every call to request.sessionSet)
    sessionTTL: 3600,

    // the cookie to use to store the session token client side, default "sid"
    sessionCookie: "session_id",
});
app.start();
