What's the best way to version CSS and JS URLs - part 2

Question

This is a follow up question on the following question What's the best way to version CSS and JS URLs

Both of the solutions mentioned there would require modification to the files where the css and js file URLs are mentioned. So in effect it would require a restart of the application server after making the changes.

Is there a better way, where versioning of static files can be handled without having to restart the Application server ?

the following is ruled out in the solution

• changing the css and js filenames
• passing a query paremeter in the url
• the solution also should not affect setting cache-control or expires.

thanks

Google's Apache module mod_pagespeed will automatically add a hash of the file to the path, to prevent old versions from the cache being used.
