Comment:

 Thank you for the ticket and patch, @geekysoft!

 That's some classic code you've run into there - the earliest instance I
 could find is [1947], but it might be from earlier. There's no ticket to
 go with it, but I suspect the original uses were based on
 [https://support.microsoft.com/en-us/kb/234067 KB234067], IE 5 and earlier
 didn't recognise `Cache-Control`, but they did recognise `Pragma` as a
 response header.

 Anyway, that was just a fun dive through history. We haven't supported
 such old browsers in a long time, so I have no problem with this going in.
