I'm trying to dynamically concatenate a bunch of _javascript_ files into a single file using the INCLUDE filter. The include.shtml.js test script is
<!--#include virtual="/static/script2.js" -->
<!--#include virtual="/static/script1.js" -->
The virtual server config has both SSIETag and SSILastModified set to On for that file
<VirtualHost *:80>
ServerName test.dkt
ServerAlias test.com
UseCanonicalName Off
ErrorLog logs/test.dkt-error_log
CustomLog logs/test.dkt-access_log combined
LogLevel info
FileEtag All
AddType application/_javascript_ .js
DocumentRoot /var/www/html/test.com
<Directory /var/www/html/test.com>
Options -Indexes
ExpiresActive Off
ExpiresDefault "access plus 1 years"
Header append Cache-Control "public"
Order deny,allow
Allow from all
</Directory>
<Directory /var/www/html/test.com/static>
<FilesMatch "\.shtml\.js$">
SSIETag On
SSILastModified On
Options +Includes
SetOutputFilter INCLUDE
</FilesMatch>
</Directory>
</VirtualHost>
It correctly serves the concatenated scripts but is always a full 200 OK in instead of a 304 Not Modified. The Firebug log

Is there a hard coded restriction on conditional requests for the INCLUDE filter?
I'm aware that I should "touch" the including script whenever there is a change in any of the included scripts. The Apache version is 2.2 running in Centos 6
