Ahora utilizaremos una dependencia simple para leer un header `X-Token` personalizado:

{* ../../docs_src/bigger_applications/app_an_py39/dependencies.py hl[3,6:8] title["app/dependencies.py"] *}

/// tip | Consejo

Estamos usando un header inventado para simplificar este ejemplo.

   *     CLEAN 1ab96a171faeeee38496d8b330771a7a 1600 234
   *     READ 335c4c6028171cfddfbaae1a9c313c52
   *     READ 3400330d1dfc7f3f7f4b8d4d803dfcf6
   *
   * The first five lines of the journal form its header. They are the constant string
   * "libcore.io.DiskLruCache", the disk cache's version, the application's version, the value
   * count, and a blank line.
