Are you sure that the server sends the header lines? As far as I remember all
of them are optional. At a first glance, it looks fine besides that - and if the
other things you added are working, these should too.
But - one other thing - you really should not edit script-files in base. If you ever
re-install bro, it will be overwritten without any warning or promoting you. Also - if
you ever update to a new version you will have to re-apply your changes manually.
Instead, you should extend the HTTP::Info record in a separate, new script-file and
also set the values in that new file by catching the http_header event.
