# limiter

[![Build Status](https://travis-ci.org/gsquire/limiter.svg?branch=master)](https://travis-ci.org/gsquire/limiter)

This is an example of `BeforeMiddleware` for the [Iron](https://github.com/iron/iron) framework.  It limits the request body size
by checking first the Content-Length header, then the size of the payload. The response is either
an HTTP 413 or it continues down the chain.

It will also set an upper bound on the length of a URL which can be helpful in regular
`GET` requests.

Include this in your `Cargo.toml` file:

```sh
[dependencies]
limiter = "0.3"
```

### Example

```rust
extern crate iron;
extern crate limiter;

use iron::prelude::*;

use limiter::RequestLimit;

fn index(_: &mut Request) -> IronResult<Response> {
    Ok(Response::with((iron::status::Ok, "Test")))
}

fn main() {
    let max_request = RequestLimit::default();
    let mut chain = Chain::new(index);
    chain.link_before(max_request);
    Iron::new(chain).http("localhost:3000").unwrap();
}
```
