Setting ExpiresByType for entire server

I run a server with several websites on it. I would like to implement default cache control behavior for all of these websites. Can I just do this by adding the following code to httpd.conf or must I make the changes in the configuration of each virtual host separately?

<IfModule mod_expires.c>
ExpiresActive on

# Your document html
ExpiresByType text/html "access plus 12 hours"

# Media: images, video, audio
ExpiresByType audio/ogg "access plus 1 month"
ExpiresByType image/gif "access plus 1 month"
ExpiresByType image/jpeg "access plus 1 month"
ExpiresByType image/png "access plus 1 month"
ExpiresByType video/mp4 "access plus 1 month"
ExpiresByType video/ogg "access plus 1 month"
ExpiresByType video/webm "access plus 1 month"

# CSS and JavaScript
ExpiresByType application/javascript "access plus 1 year"
ExpiresByType text/css "access plus 1 year"

# Default
ExpiresDefault "access plus 1 month"
</IfModule>

Documentation can be found in the Apache HTTP Server web site. In the "Documentation" section on the left pane, click on your server version. I'll assume 2.4. Since you are looking for reference on specific directives, you can click on the Directives link. You'll get an alphabetical index.

I won't copy the complete information, just a little sample for ExpiresActive. The important bit is the top table:

Description: Enables generation of Expires headers
Syntax:      ExpiresActive On|Off
Default:     ExpiresActive Off
Context:     server config, virtual host, directory, .htaccess
Override:    Indexes
Status:      Extension
Module:      mod_expires

At "Context" we can read that the directive can be set at several places, including server config. So this answers your question: in theory, it should work. You should check the rest of the directives in order to make sure (or just test it).
