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

### Bug or Regression

to curtsey as she spoke--fancy CURTSEYING as you're falling
through the air!  Do you think you could manage it?)  `And what
an ignorant little girl she'll think me for asking!  No, it'll
never do to ask:  perhaps I shall see it written up somewhere.'

  Down, down, down.  There was nothing else to do, so Alice soon
began talking again.  `Dinah'll miss me very much to-night, I
