/**
 * Represents a hierarchical trace of nested requests within a session, enabling correlation between
 * session events and their originating operations in the application code. The trace structure
 * supports the following key features:
 *
 * <ul>
 *   <li>Maintains parent-child relationships between requests to track operation nesting</li>
 *   <li>Carries contextual data describing the current request or operation</li>

В этом примере мы используем выдуманные пользовательские HTTP-заголовки `X-Key` и `X-Token`.

Но в реальных проектах, при внедрении системы безопасности, вы получите больше пользы используя интегрированные [средства защиты (следующая глава)](../security/index.md).
