Wrong headers in get.inc for nginx and IE 7

[harmaty]

Browser: Internet Explorer 7
HTTP-server: nginx

When I try to download attached archive I get alert:
"Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later."

In Firefox it works.

forgot to say: protocol is HTTPS

I have added two headers in program/steps/mail/get.inc:

      header('Pragma: ');
      header('Cache-Control: ');

And now it works for all browsers.

In function send_nocacheing_headers() (rcube_shared.inc) we have

  if (isset($_SERVER['HTTPS'])) {
    header('Pragma: ');
    header('Cache-Control: ');
  }

Looks like nginx doesn't provide this property. Could you determine what variable we could check instead? Using $_SERVER['SERVER_PORT'] is not absolutely reliable.

I'm not a nginx guru, but it's possible to set $_SERVERHTTPS? in vhost config:

fastcgi_param HTTPS on;

[harmaty]

Yes, if we add "fastcgi_param HTTPS on;" to nginx config, $_SERVERHTTPS? will appear.

Unfortunately, there are no other variables, except $_SERVERSERVER_PORT?, to detect the protocol

[alec]

So, a new config option or just a hint in INSTALL file? We're checking HTTPS variable also in iniset.php, so config option would be problematic. BTW, nginx is not listed in INSTALL file as supported server.

[alec]

We've got also request for an option in #1485655

Added 'use_https' option in [161c28df].
