Mod_Deflect Enabled - Not detecting

I am following this tutorial on how to enable mod_deflect for apache2

http://www.howtoforge.com/apache2_mod_deflate

I am using apache 2.2 from ISPConfig and multiphp version 5.5 , 5.6

I added this in my global apache conf file.

Code:

/etc/apache2/apache.conf

at the end.

Code:

# Custom Configuration WordPress W3Total Cache

SetOutputFilter DEFLATE
SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ \
    no-gzip dont-vary
SetEnvIfNoCase Request_URI \
    \.(?:exe|t?gz|zip|bz2|sit|rar)$ \
    no-gzip dont-vary
SetEnvIfNoCase Request_URI \.pdf$ no-gzip dont-vary

BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html

DeflateFilterNote Input input_info
DeflateFilterNote Output output_info
DeflateFilterNote Ratio ratio_info
LogFormat '"%r" %{output_info}n/%{input_info}n (%{ratio_info}n%%)' deflate
CustomLog /var/log/apache2/deflate_log deflate

Then I make apache2 restart. I also check if it got enabled in server using command and it says enabled. But if I go to my plugin for checking it then It is not detecting. It shows me this -

Code:

 
mod_deflate: Not detected (required for disk enhanced Page Cache and Browser Cache)
mod_env: Not detected (required for disk enhanced Page Cache and Browser Cache)
mod_expires: Not detected (required for disk enhanced Page Cache and Browser Cache)
mod_headers: Not detected (required for disk enhanced Page Cache and Browser Cache)
mod_mime: Not detected (required for disk enhanced Page Cache and Browser Cache)
mod_rewrite: Not detected (required for disk enhanced Page Cache and Browser Cache)
mod_setenvif: Not detected (required for disk enhanced Page Cache and Browser Cache) 

Any suggestion would be appreciate for fixing it.

Thanks.

 

Ah

I am using Fast-Cgi.

So mod_deflect doesn't work with it?.

 

I see! Thanks!
