Hi Nick.
No need to get upset.
As I understand the issue now (and as stated above by the OP), 
mod_deflate seems to be doing fine in most cases.
However, it also seems that /some/ pages which are rendered by something 
("Actuate 8 report server", which I have no idea what it is) are 
actually compressed (?), but do /not/ come out with the correct 
 From all that, I gather (now) that these specific pages are not static, 
but generated on-the-fly (Arabinda, is that right ?).
So the question now would be : is there something (in the URI used to 
request such a page for example) that allows to distinguish it from 
other pages that do work ?
And does the problem concern /all/ the pages produced by that "Actuate 8 
report server", or just some of them ?

Also (for Nick), while we are at it, /why/ would it be that a 
content-encoding response header set unconditionally by mod_headers 
would not come out ?
(the OP earlier posted the "Header" line used.)
