Using query strings to manage cached assets is unreliable - some caching proxies ignore query strings. Fingerprinted file names is a better solution and recommended by Google. There's an AssetFingerprint plugin to help with this which I'm shamelessly plugging: http://blog.eliotsykes.com/2010/05/06/why-rails-a...

I think you're right Mike, FilesMatch doesn't match against the query string. I've been using ERB to render my stylesheets so that they do include time stamps, I wrote about it here: http://deaddeadgood.com/2009/9/28/far-future-expi...

Oops, comment editor swallowed my example code–must not like angle brackets. My example just added a backslash before the '?' and 'd' in the regexp.

If this was possible, I think the '?' and 'd' in that regex would need to be escaped as follows:

I believe, however, that it will not work. I tried this a number of different ways and it appears that the Apache directive ignores the '?' and everything that follows. Otherwise, how could 'myimage.jpg?1234567890' possibly match a regexp ending in "$" (which means string ends here)? I did some tests and this is in fact the case–timestamped assets are matched by the original regex and fail to match with any additions after the file extension.

After trying a few variations I found I needed to add

ExpiresActive on

to get the Expires headers working. Though I still cannot get the regexp for the timestamps to work. I have tried a few variations that work in Perl/Ruby but I get no results in Apache.

Anyone have a working example that handles timestamps?

Good tip, don't forget to mention you need to enable mod_deflate also: a2enmod deflate in order for the gzipping to work.

Also, the a2enmod scripts are debian specific i believe? other [lame] distros might need to manually add the module.

And, couldn't get josh's code to work, kept saying my css files didn't have expires headers

Thanks, Josh! I'll give that a try. Seems like it would work well to me.

This would do the trick wouldn’t it: # gzip html, css and js AddOutputFilterByType DEFLATE text/html text/css application/x-javascript application/javascript # far future expires headers ExpiresDefault "access plus 10 years"

Yeah, I guess not. Any chance of getting some pointers on how to fix this?
