Caching
=======

OkHttp implements an optional, off by default, Cache. OkHttp aims for RFC correct and
pragmatic caching behaviour, following common real-world browser like Firefox/Chrome and 
server behaviour when ambiguous.

# Basic Usage

```kotlin
  private val client: OkHttpClient = OkHttpClient.Builder()
      .cache(Cache(
          directory = File(application.cacheDir, "http_cache"),
          // $0.05 worth of phone storage in 2020

{* ../../docs_src/custom_response/tutorial009c_py39.py hl[9:14,17] *}

Now instead of returning:

```json
{"message": "Hello World"}
```

...this response will return:

```json
{
  "message": "Hello World"
}
```

Of course, you will probably find much better ways to take advantage of this than formatting JSON. 😉

{* ../../docs_src/custom_response/tutorial009c_py39.py hl[9:14,17] *}

Statt:

```json
{"message": "Hello World"}
```

... wird die Response jetzt Folgendes zurückgeben:

```json
{
  "message": "Hello World"
}
```

Natürlich werden Sie wahrscheinlich viel bessere Möglichkeiten finden, Vorteil daraus zu ziehen, als JSON zu formatieren. 😉
