# Install

To install via [Composer](http://getcomposer.org/), use the command below, it will automatically detect
the latest version and bind it with `^`.

```
composer require wyrihaximus/react-http-middleware-response-cache
```

This middleware caches the response code and body from a list of given URL's. Note that not headers will be
cached at this point. The middleware accepts a cache configuration implementing `CacheConfigurationInterface`
as first argument which will decide when to store something in the cache and what. As second argument it
accepts a cache implementing [`CacheInterface`](https://reactphp.org/cache/#cacheinterface) so either
[`ArrayCache`](https://reactphp.org/cache/#arraycache) shipping with [`react/cache`](https://reactphp.org/cache/)
or any cache implementing [`CacheInterface`](https://reactphp.org/cache/#cacheinterface) from the
[cache implementations](https://github.com/reactphp/react/wiki/Users#cache-implementations) listed at
the [ReactPHP users wiki](https://github.com/reactphp/react/wiki/Users).

# Usage

```php
$server = new Server([
/** Other middleware */
new ResponseCacheMiddleware(
new CacheConfiguration(
[
'/',
'/robots.txt',
'/favicon.ico',
'/cache/***', // Anything that starts with /cache/ in the path will be cached
'/api/???', // Anything that starts with /cache/ in the path will be cached (query is included in the cache key)
],
[ // Optional, array with headers to include in the cache
'Content-Type',
]
),
new ArrayCache() // Optional, will default to ArrayCache but any CacheInterface cache will work.
),
/** Other middleware */
]);
```

# Sessions

Using this middleware together with [`wyrihaximus/react-http-middleware-session`](https://github.com/WyriHaximus/reactphp-http-middleware-session) then
please take a look at [`wyrihaximus/react-http-middleware-response-cache-session-cache-configuration`](https://github.com/WyriHaximus/reactphp-http-middleware-response-cache-session-cache-configuration) to
ensure you don't serve cached responses to users with active sessions.
