# Sessions for Rocket.rs
Adding cookie-based sessions to a rocket application is extremely simple:
```rust
#![feature(proc_macro_hygiene, decl_macro)]
#[macro_use] extern crate rocket;
use rocket_session::Session;
use std::time::Duration;
fn main() {
rocket::ignite()
.attach(Session::fairing(Duration::from_secs(3600)))
.mount("/", routes![index])
.launch();
}
#[get("/")]
fn index(session: Session) -> String {
let mut count: usize = session.get_or_default("count");
count += 1;
session.set("count", count);
format!("{} visits", count)
}
```
Anything serializable can be stored in the session, just make sure to unpack it to the right type.
The session driver internally uses `serde_json::Value` and the `json_dotpath` crate.
Therefore, it's possible to use dotted paths and store the session data in a more structured way.
