possibble to use fastcgi cache with set-cookie header

[Jools Wills]

> fastcgi_ignore_headers Cache-Control Expires;

Changing this to

fastcgi_ignore_headers Cache-Control Expires Set-Cookie;

seems to do the job, but this is not documented anywhere I could find 
(not on the wiki for example). Is this correct? if so, I'll add it to 
the wiki (and if it is what version was this introduced?)

I'm running nginx 0.8.49 btw.

Best Regards
