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

      this.fromList = checkNotNull(fromList);
      this.function = checkNotNull(function);
    }

    /**
     * The default implementation inherited is based on iteration and removal of each element which
     * can be overkill. That's why we forward this call directly to the backing list.
     */
    @Override
    protected void removeRange(int fromIndex, int toIndex) {

   *
   * <p>This workaround should be removed at a distant future time when <a
   * href="https://issuetracker.google.com/issues/115932459">Android supports {@code
   * AnnotatedType}</a>.
