The current approach to gzip compression is fundamentally flawed. See bug46538
and bug39727 for an explanation of why. Transfer-Encoding is the correct way to
go but browser support is still patchy.

That said, the majority of the current botched solutions - Tomcat included - do
set the Vary header. The proposed patch isn't quite right - see bug 48660 for
details.

I have applied a corrected patch to to 7.0.x and it will be included in 7.0.1
onwards.
