Deflate - Logging ratios

[Anantha Padmanabha <anantha.padmanabha@xxxxxxxxxxxxxx>]

Hi,

I am using Apache 2.2.8. I tried to add logging for deflate [gzip] ratios in a dev machine by looking at http://httpd.apache.org/docs/2.0/mod/mod_deflate.html and some other articles on internet.

Heres the configuration used:
<IfModule mod_deflate.c>
   AddOutputFilterByType DEFLATE text/html text/plain text/xml
</IfModule>

DeflateFilterNote Input instr
DeflateFilterNote Output outstr
DeflateFilterNote ratio
LogFormat "%h\t%l\t%u\t%t\t\"%r\"\t%>s\t%b\t%D\t\"%{User-Agent}i\"\t%I\t%O\t%{outstr}n/%{instr}n\t(%{ratio}n)" common

Logging is working fine but the ratio is not appearing for html files [It gets printed for css/js files]

192.168.0.57    -       -       [28/Jul/2009:17:56:57 +0530]    "GET /credit-card/apply-online.html HTTP/1.1"   200     14722   418995  "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1) Gecko/20090624 Firefox/3.5"  1257    15257   -/-     (-)
192.168.0.57    -       -       [28/Jul/2009:17:56:58 +0530]    "GET

Firefox/3.5"  1225    2974    2307/9821       (23)

I verified using lwp-request, curl and online tools that our configs are compressing pages while serving.
anantha@anantha-laptop:~$ lwp-request -e -d -H 'Accept-Encoding: gzip' http://local.bankbazaar.com/ |grep -i -e Content-Encoding -e Content-Length
Content-Encoding: gzip
Content-Length: 8793

Please help me understand why ratio is not appearing for html files.

Thanks
Anantha
