Can dispatcher re-cache updated JS or CSS file?

When user browses certain page, dispatcher will cache js and css the page using, like /apps/project/components/componentA/clientlibs.css. 

While if the css or js (under clientlibs folder) is updated on Author and Publish, will the dispatcher re-cache this updated file like html page does? 

In my environment it seems that dispatcher will not re-cache css or js. Am I missing some configure or is dispatcher unable to sence css and js update?

In the dispatcher.any invalidate section you can add css js so that it can gets invalidate.   As changes to js/css very minimal after launch rather than auto invalidating manual clearing the cache is preffered.

You can use mod_expires module from apache[1] for this. Setting like this could avoid permanent caching

# enable expirations
ExpiresActive On
# Image - 1 Month; JS,CSS - 1 Hour; font - 1 week
ExpiresByType image/gif "access plus 1 month"
ExpiresByType application/javascript "access plus 1 hour"
ExpiresByType application/x-javascript "access plus 1 hour"
ExpiresByType text/css "access plus 1 hour"
ExpiresByType image/png "access plus 1 month"

ExpiresByType application/octet-stream "access plus 1 week"

else you might have to write your own custom sling rewriter

For the documentation, see the "Automatically Invalidating Cached Files" section below http://docs.adobe.com/docs/en/dispatcher/disp-config.html#Configuring%20the%20Dispatcher%20Cache
