DESCRIPTION
modgzip2dlf converts web server log file in the common log format with
extensions for mod_gzip to www DLF.
mod_gzip is an Apache extension developed by RemoteCommunications, Inc.

informations can be found at
http://www.RemoteCommunications.com/apache/mod_gzip/mod_gzip_faq.htm.
mod_gzip can log informations about the compression of pages by
configuring Apache to log using the ’gzip’ format which can be defined
as follows:
LogFormat "%h %l %u %t \"%r\" %>s %b %{mod_gzip_result}n %{mod_gzip_compression_ratio}n" gzip
MOD_GZIP EXTENSIONS
The mod_gzip extensions adds two fields to the Common Log Format; see
common2dlf(1):
gzip_result compression_ratio
gzip_result
The gzip’s result code. Usually OK.
compressio_ratio

100.

by lr_log2report:
