582042 - Platform detection in Zeus

Status: RESOLVED FIXED

(mozilla.org Graveyard :: Server Operations, task)

Description

[Alex Buchanan [:abuchanan]]

Implementing simple platform detection in Zeus and setting a custom header with the result, e.g. Moz-Platform: MacOSX, would allow us to Vary: Moz-Platform, which would simplify our download button code on mozilla.com (and make our pages faster too).

The TrafficScript would look something like,

$ua = http.getHeader("User-Agent");

$os_windows = 'windows';
$os_mac = 'mac';
$os_mac_osx = 'macosx';
$os_linus = 'linux';
$os_solaris = 'solaris';
$os_other = 'other';
$os = $os_other;

if (string.find("Win32", $ua) != -1 || string.find("Win64", $ua) != -1)
  $os = $os_windows;
else if (string.find("Linux", $ua) != -1)
  $os = $os_linux;
else if (string.find("Mac OS X", $ua) != -1)
  $os = $os_macosx;
else if (string.find("MSIE 5.2"", $ua) != -1)
  $os = $os_macosx;
else if (string.find("Mac"", $ua) != -1) {
  $os = $os_mac;

  # Special case for Opera on OS X emulating IE (bug 402113)
  if ((string.find("Opera"", $ua) != -1) && (string.find("Opera 6"", $ua) == -1))
    $os = $os_macosx;

} else if (string.find("SunOS", $ua) != -1)
  $os = $os_solaris;
else
  $os = $os_other;

http.addHeader('Moz-Platform', $os);


What do you think?  Good idea?  Terrible idea?

ah, ok thanks.  no, it can wait.

I have this traffic script in Zeus, and the header will be "X-Moz-Platform" where should I enable to test it out?

Comment 6

[Alex Buchanan [:abuchanan]]

How about www-trunk.stage?  Or, even mozilla.com production, since it's an extra header, it shouldn't disrupt anything.

I've added this to production. www-trunk.stage is still behind the netscaler.
