Hi,

This isn't a complete solution and I'm not an expert on Apache but I have been looking at compression over the last couple of days and found that the following lines work. They are less verbose than those you are currently using and so possibly easier to edit to meet your requirements:

##ZIP/DEFLATE/COMPRESS
AddOutputFilterByType DEFLATE text/html text/plain text/xml text/javascript text/css
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html
Header append Vary User-Agent env=!dont-vary
##LOG FOR ZIP/DEFLATE/COMPRESS
DeflateFilterNote deflate_ratio
LogFormat "%v %h %l %u %t \"%r\" %>s %b mod_deflate: %{deflate_ratio}n pct." vhost_with_deflate_info
CustomLog /var/log/deflate_access_log vhost_with_deflate_info

The log lines are useful because they show how much pages are being compressed, but if you do not want to know then omit them.

well that is fine ... i specifically want to compress only css files for IE 6.0 and rest of the files should be uncompressed and for other browsers it should compress every thing except image file(png, gpeg..exc) and pdf files...the above code doesn't do that...

You may try the following snipped (mod_rewrite required).
LoadModule deflate_module @@APACHE_DIR@@/modules/mod_deflate.so
 
RewriteEngine on
RewriteCond %{HTTP_USER_AGENT} ^Mozilla/4
RewriteCond %{HTTP_USER_AGENT} !MSIE
RewriteRule  ^ - [NS,E=gzip-only-text/html,L]
 
RewriteCond %{HTTP_USER_AGENT} ^Mozilla/4\.0[678]
RewriteCond %{HTTP_USER_AGENT} !MSIE
RewriteRule  ^ - [NS,E=no-gzip,L]
 
RewriteCond %{HTTP_USER_AGENT} MSIE\ 6\.0
RewriteRule !\.(?:css|js)$ - [NS,E=no-gzip,L]
 
<Location />
AddOutputFilterByType DEFLATE text/plain text/xml text/css text/javascript text/html
# Make sure proxies don't deliver the wrong content
Header append Vary User-Agent env=!dont-vary
