 Here's what I've been doing...  It saves a lot of space, especially
 on the laptop.

--- from /etc/apache/srm.conf ------

# So I can gzip the html files in "/usr/doc"
AddType text/x-html-gzip htmlgz
AddHandler x-html-gzip htmlgz
Action x-html-gzip /cgi-bin/zcat-html

AddType text/x-plain-gzipped .gz
AddHandler x-plain-gzipped .gz
Action x-plain-gzipped /cgi-bin/zcat-plain

# ... or bzip2 them.
AddType text/x-html-bzip2 htmlbz2
AddHandler x-html-bzip2 htmlbz2
Action x-html-bzip2 /cgi-bin/bz2cat-html

AddType text/x-plain-bzip2ed .bz2
AddHandler x-plain-bzip2ed .bz2
Action x-plain-bzip2ed /cgi-bin/bz2cat-plain
