I trawled around but just don't seem to be able to get to the bottom of this one. Is it suitable to use these two together?
# cache scripts, css, and documents for 1 week, do not require revalidation
<FilesMatch "\.(js|css|pdf)$">
Header set Cache-Control: "max-age=604800"
</FilesMatch>
<FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css)$">
Header unset Last-Modified
</FilesMatch>
....
I note on askapache
By also including a Cache-Control header and Expires header, you can specify that certain files be cached for a certain period of time, and you magically (this is a really unique trick I promise) eliminate any validation requests!
Should they be combined somehow or is there a rule for ordering of FilesMatch? Then I then dont fully understand the introduction of an expires header
<FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)$">
Header set Expires "Thu, 15 Apr 2010 20:00:00 GMT"
</FilesMatch>
in terms of how to marry up the Cache-control Max-age and the Expires date?
I think i've been looking at this too long and now can't see the wood for the trees! :-)
thanks,
Mick
