Flash in any browser does not understand gzipping and this is well known
fact, at least for me :). I developed mod_deflate for Apache 1.3 long ago
and had documented this here (in Russian):


So the single way is disable gzip in locations which are requested
from Flash. It is not depeneded on browser.
