Apache<->CSP<->deflate/gzip

[Gyetvan Andras]

Hi All !
I am interested in to compress CSPs output. My application uses Cache as 
a WebService server and I would like to compress the content soming from 
the Cache.
I am using Apache 2 and tried mod_deflate, mod_gzip, none of them work. 
I can compress "static" content (i.e. : the Apache manual), but I had no 
success with CSP. Here is an excerpt from the httpd.conf file :

LoadModule deflate_module /usr/lib/httpd/modules/mod_deflate.so
#### BEGIN-ApacheCSP-SECTION ####
ScriptAliasMatch /*.([Cc][Ss][Pp]|[Cc][Ll][Ss])$ 
"/usr/cache/csp/bin/nph-CSPcgi"

Alias /csp/ /usr/cache/csp/
<Directory "/usr/cache/csp/">
        SetOutputFilter DEFLATE
        AddOutputFilterByType DEFLATE text/*
        AddOutputFilter DEFLATE cls csp
        AllowOverride None
        Options MultiViews FollowSymLinks ExecCGI
        Order allow,deny
        Allow from all
        <Files CSPnsd>
                 Deny from all
        </Files>
        <Files CSP.ini>
                 Deny from all
        </Files>
        <Files CSP.log>
                 Deny from all
        </Files>
        <Files CSPnsd.ini>
                 Deny from all
        </Files>
        <Files CSPnsd.pid>
                 Deny from all
        </Files>
        <FilesMatch "\.(log|ini|pid)$">
                Deny from all
        </FilesMatch>
</Directory>
ScriptAlias /csp-bin/ "/usr/cache/csp/bin/"
<Directory "/usr/cache/csp/bin/">
        SetOutputFilter DEFLATE
        AddOutputFilterByType DEFLATE text/*
        AddOutputFilter DEFLATE cls csp
        AllowOverride None
        Options None
        Order allow,deny
        Allow from all
</Directory>
Action text/csp "/csp-bin/nph-CSPcgi"
#### END-ApacheCSP-SECTION ####
What I miss ? Is it possible at all ?
Thanks for advance,
Andras
