I prefer hashes to timestamps (with multiple web-servers timestamps may not be identical) and have an irrational dislike for using the query-string like this. @Reggie: Yes, the rewrite rule has essentially the same effect. @a: ETags are used for cache validation, i.e. you don't know if your cached object is fresh, and the web server returns a 304 if it is by comparing the Etags. So this will save bandwidth, but not reduce the number of requests. @Moshe & Adam: That’s what Rails does, and it works (as long as you have an expires-tag, otherwise it’s useless).

Seems that href="/css/main.css?c0a9a0a5ec" would do just as well. So why use a rewrite rule at all? Seems that href=”/css/main.css?c0a9a0a5ec” would do just as well.

Save the filename as is "whatever.js". Now to do the versioning you append a "?" on the end and add the file modification date. So you end up with whatever.js?1217141507. Now whenever you make a change the version is automatically updated. Theres an easier way to do static file caching… Save the filename as is “whatever.js”.
