Hallo Michael,
thanx a lot for your second answer!!
Now I have a better understanding of the filter settings.
I have managed to find a filter configuration that works!! :-)
# Phase 1: (reqheader, uri, file, handler)
# =
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
mod_gzip_item_exclude reqheader "User-agent:
Mozilla/4.0[678]"
mod_gzip_item_include file \.html$
mod_gzip_item_include file \.jsp$
mod_gzip_item_include file \.jsp
mod_gzip_item_include uri \.jsp$
mod_gzip_item_include uri \.jsp
mod_gzip_item_exclude file \.js$
mod_gzip_item_exclude file \.css$
mod_gzip_item_include file \.pl$
mod_gzip_item_include handler ^cgi-script$
#
# Phase 2: (mime, rspheader)
# =
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D
mod_gzip_item_include mime ^text/*$
mod_gzip_item_include mime ^text/.*$
mod_gzip_item_include mime ^httpd/unix-directory$
mod_gzip_item_exclude mime ^image/
I don't know if these setting are a 'minimal' solution or if I can
delete some line, but it works! :-)
so, again
Thank you,
ciao Markus
