Handling duplicate headers

[Felix]

Hi all,

Just a question about handling duplicate headers. I am currently using
Chrome and trying to get it to pass to the backend on a client forced
refresh. Chrome sends the following headers:

  RxHeader     c Cache-Control: max-age=0
  RxHeader     c Cache-Control: no-cache

and I have been trying to catch 'no-cache' but it never gets it with
this rule:

  if (req.http.Cache-Control ~ "no-cache")

as it seems to fill the 'Cache-Control' header spot with the first one
it finds, 'max-age'

Is there a way to cope with this or is this a bug?
