你應該會看到一個很長的 **ReDoc** JavaScript 檔案。

它可能會以如下內容開頭：

```JavaScript
/*! For license information please see redoc.standalone.js.LICENSE.txt */
!function(e,t){"object"==typeof exports&&"object"==typeof module?module.exports=t(require("null")):
...
```

這表示你的應用已能提供靜態檔案，且文件用的靜態檔已放在正確位置。

接著把應用設定為讓文件使用這些靜態檔。

### 為靜態檔案停用自動文件 { #disable-the-automatic-docs-for-static-files }

Şuna benzer bir şekilde başlayabilir:

```JavaScript
/*! For license information please see redoc.standalone.js.LICENSE.txt */
!function(e,t){"object"==typeof exports&&"object"==typeof module?module.exports=t(require("null")):
...
```

Bu, uygulamanızdan statik dosyaları servis edebildiğinizi ve dokümanlar için statik dosyaları doğru yere koyduğunuzu doğrular.

* For HTTPS, **the server** needs to **have "certificates"** generated by a **third party**.
    * Those certificates are actually **acquired** from the third party, not "generated".
* Certificates have a **lifetime**.
    * They **expire**.
    * And then they need to be **renewed**, **acquired again** from the third party.
* The encryption of the connection happens at the **TCP level**.
    * That's one layer **below HTTP**.
