NAME

       modgzip2dlf - convert Common Log Format with mod_gzip extensions web server log files to
       DLF

SYNOPSIS

       modgzip2dlf file

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. Sourcecode is free
       available from http://www.RemoteCommunications.com/apache/mod_gzip/mod_gzip. More
       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
           The ratio by which the content was compressed. A number from 0 to 100.

       Log example :

         127.0.01 - - [11/03/2001 12:12:01 -0400] "GET / HTTP/1.0" 200 252 "-" "Mozilla/5.0" OK 49
         dsl1.myprovider.com - francis [11/03/2001 12:14:01 -0400] "GET /secret/ HTTP/1.0" 200 300 "http://www.example.com/index.html" "Mozilla/5.0" OK 74

EXAMPLES

       To process a log as produced in the modgzip logformat:

        $ modgzip2dlf < common.log

       modgzip2dlf will be rarely used on its own, but is more likely called by lr_log2report:

        $ lr_log2report modgzip < /var/log/httpd/common.log
