Add the Forwarded-Host header

How can I add the Forwarded-Host header?
For security reasons, I need to add the Forwarded-Host header to my website, but I have no idea how to implement this.
In the file called rewrite.rules I added the code (dispatcher > conf.d > rewrites > rewrite.rules):

<IfModule mod_headers.c>
    RequestHeader set Forwarded-Host "%{Host}e" env=Host
</IfModule>

But it didn't solve my problem of adding the Forwarded-Host.

    Hi @EvertonSa2,

    rewrite rules are added in the mod_rewrite section of your VHOST file. Add your custom header directly under VirtualHost in the VHOST file. For example:

     

    # Add Forwarded-Host header RequestHeader set Forwarded-Host "%{HTTP_HOST}e"

     

     

    Good luck,

    Daniel

      Mas em qual arquivo exatamente eu adiciono esse trecho de código: 

      # Add Forwarded-Host header
RequestHeader set Forwarded-Host "%{HTTP_HOST}e"

      Não posso modificar o arquivo default.vhost, porque se eu modifica-lo a pipeline da erro.
      Os arquivos que possuo são:
      dispatcher > src > conf.d > enabled_vhosts > default.vhost
      dispatcher > src > conf.d > enabled_vhosts > custom_headers.conf

      dispatcher > src > conf.d > available_vhosts > default.vhost
      dispatcher > src > conf.d > rewrites > default_rewrite.rules
      dispatcher > src > conf.d > rewrites > rewrite.rules

      @EvertonSa2 let's please stick to English, so I dont have to Google Translate your question 🙂

      You should create your own VHOST file, not edit the default one. It is clearly stated in the AEM archetype: https://github.com/adobe/aem-project-archetype/blob/develop/src/main/archetype/dispatcher.cloud/src/...

      Also, you did not mention if you are using AEM on Prem or AEMaaCS. Please refer to the relevant Dispatcher documentation from Adobe. Both are well documented.

       

      Good luck,

      Daniel
