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

And, for example, you will probably see that there are multiple processes running the same browser program (Firefox, Chrome, Edge, etc). They normally run one process per tab, plus some other extra processes.

- 行程可以被你或作業系統終止（kill）。此時它就停止執行，無法再做任何事。
- 你電腦上執行的每個應用程式、每個視窗等，背後都有一些行程。而且在電腦開機時，通常會同時有許多行程在跑。
- 同一個程式可以同時有多個行程在執行。

如果你打開作業系統的「工作管理員」或「系統監控器」（或類似工具），就能看到許多正在執行的行程。

例如，你大概會看到同一個瀏覽器（Firefox、Chrome、Edge 等）會有多個行程在執行。它們通常每個分頁一個行程，外加其他一些額外行程。

現在我們知道「行程」與「程式」的差異了，繼續談部署。

İşletim sisteminizdeki "task manager" veya "system monitor" (ya da benzeri araçlar) ile bu process'lerin birçoğunu çalışır halde görebilirsiniz.

Örneğin muhtemelen aynı browser programını (Firefox, Chrome, Edge vb.) çalıştıran birden fazla process göreceksiniz. Genelde her tab için bir process, üstüne bazı ek process'ler çalıştırırlar.

        // file
        assertUrlLink("file:/home/taro/test.txt", //
                "file://home/taro/test.txt");
        assertUrlLink("file:/home/taro/あ.txt", //
                "file://home/taro/あ.txt");
        assertUrlLink("file:/home/taro/%E3%81%82.txt", //
                "file://home/taro/あ.txt");

        // smb->file
        assertUrlLink("smb:/home/taro/test.txt", //
                "file://home/taro/test.txt");

Например, вы, скорее всего, увидите несколько процессов одного и того же браузера (Firefox, Chrome, Edge и т.д.). Обычно браузеры запускают один процесс на вкладку плюс дополнительные процессы.
