¿Cómo reconstruyo la cookie de solicitud en barniz vcl?

Question

No estoy seguro de si estoy haciendo la pregunta correcta. Tengo barniz sentado frente a un sitio que tiene acceso a numerosas cookies. Las más importantes son Creds Cookie. Lo que estoy haciendo es quitar todas las galletas que no necesito y luego verificar si se queda alguna cookie. Si es así, esto significa que omitimos el barniz, de lo contrario, devuelva el objeto de caché.

  # Remove all cookies that Drupal doesn't need to know about. We explicitly 
  # list the ones that Drupal does need, the SESS , NO_CACHE and credential cookie namely  auth 
  #. If, after running this code we find that either of these two cookies remains, we 
  # will pass as the page cannot be cached.
  if (req.http.Cookie) {
    # 1. Append a semi-colon to the front of the cookie string.
    # 2. Remove all spaces that appear after semi-colons.
    # 3. Match the cookies we want to keep, adding the space we removed 
    #    previously back. (\1) is first matching group in the regsuball.
    # 4. Remove all other cookies, identifying them by the fact that they have
    #    no space after the preceding semi-colon.
    # 5. Remove all spaces and semi-colons from the beginning and end of the 
    #    cookie string. 
    set req.http.Cookie = ";" + req.http.Cookie;
    set req.http.Cookie = regsuball(req.http.Cookie, "; +", ";");    
    set req.http.Cookie = regsuball(req.http.Cookie, ";(SESS[a-z0-9]+|SSESS[a-z0-9]+|NO_CACHE+|auth)=", "; \1=");
    set req.http.Cookie = regsuball(req.http.Cookie, ";[^ ][^;]*", "");
    set req.http.Cookie = regsuball(req.http.Cookie, "^[; ]+|[; ]+$", "");

    if (req.http.Cookie == "") {
      # If there are no remaining cookies, remove the cookie header. If there
      # aren't any cookie headers, Varnish's default behavior will be to cache
      # the page.
      unset req.http.Cookie;
    }
    else {
      # If there is any cookies left (a session or NO_CACHE cookie), do not
      # cache the page. Pass it on to Apache directly.
      return (pass);
    }
  }
}

Esto funciona bien. Me faltan un caché cuando auth Cookie está allí y un éxito de lo contrario. Sin embargo, incluso cuando es una señorita, parece que el barniz pasa la solicitud sin el resto de las cookies que vinieron en la solicitud. ¿Hay alguna forma de dirigir el barniz para pasar el Cooke original?

Quizás algo como

else {
  # If there is any cookies left (a session or NO_CACHE cookie), do not
  # cache the page. Pass it on to Apache directly.
  # And set the cookie to its original form ??
  return (pass);
}

Puede copiar cookie original antes de analizarla y restaurarla else Declaración, algo como:

  # ....
  # Store original cookie in other headder
  set req.http.X-Cookie = req.http.Cookie;
  if (req.http.Cookie) {
    # ... 
    set req.http.Cookie = ";" + req.http.Cookie;
    set req.http.Cookie = regsuball(req.http.Cookie, "; +", ";");    
    set req.http.Cookie = regsuball(req.http.Cookie, ";(SESS[a-z0-9]+|SSESS[a-z0-9]+|NO_CACHE+|auth)=", "; \1=");
    set req.http.Cookie = regsuball(req.http.Cookie, ";[^ ][^;]*", "");
    set req.http.Cookie = regsuball(req.http.Cookie, "^[; ]+|[; ]+$", "");

    if (req.http.Cookie == "") {
      # ....
      # Delete cookie copy
      unset req.http.X-Cookie;
      unset req.http.Cookie;
    }
    else {
      # ...
      # Restore original cookie and delete the copy
      set req.http.Cookie = req.http.X-Cookie;
      unset req.http.X-Cookie;
      return (pass);
    }
  }
}
