여기에서는 **여러 주제**에 대한 다양한 레시피(“how to” 가이드)를 볼 수 있습니다.

대부분의 아이디어는 어느 정도 **서로 독립적**이며, 대부분의 경우 **여러분의 프로젝트**에 직접 적용되는 경우에만 학습하면 됩니다.

프로젝트에 흥미롭고 유용해 보이는 것이 있다면 확인해 보세요. 그렇지 않다면 아마 건너뛰어도 됩니다.

Hier finden Sie verschiedene Rezepte und „How-To“-Anleitungen zu **verschiedenen Themen**.

Die meisten dieser Ideen sind mehr oder weniger **unabhängig**, und in den meisten Fällen müssen Sie diese nur studieren, wenn sie direkt auf **Ihr Projekt** anwendbar sind.

Wenn etwas für Ihr Projekt interessant und nützlich erscheint, lesen Sie es, andernfalls überspringen Sie es einfach.

### 代理轉發標頭如何運作 { #how-proxy-forwarded-headers-work }

以下是「代理」在用戶端與「應用伺服器」之間加入轉發標頭的視覺化示意：

    try {
      /*
       * Converter.apply has a non-nullable parameter type but doesn't throw for null arguments. For
       * more information, see the comments in that class.
       *
       * We already know that that's how it behaves, and subclasses of Converter can't change that
       * behavior. So there's no sense in making all subclass authors exclude the method from any
       * NullPointerTester tests that they have.
