First, apologizes if this post is not in the right category.
I have this in my apache configuration.

For some odd reason, several months after I implemented this to the config, I've been noticing that the expires date haven't changed.
For example
In yslow I'm getting things like:
(2009/10/13) http://www.example.com/_includes/file.swf
When it was first implemented it had a good expiry date on there. At this point though, it's no longer effective.
Any idea what I might need to update/change to force a date change?
