Looking at
http://php.net/manual/de/function.header.php and
http://joseph.randomnetworks.com/2004/10/01/making-ie-accept-file-downloads/

it seems that IE needs this Pragma: Public for caching on
https-connections, as IE by default does not cache (or in any other way
save to disk) any encrypted content.

So it should stay there unless a real problem gets reported.

-1 from me.
