Very interesting article. This would be great to have on JavaLobby. If you’re interested, send me a mail and we can organise it.

Thanks James

Isn’t 1 year or 10 years overkill? Most browsers will download it again the next day because the disk caches are set (by default) to relatively small sizes. Also, if your server shows the last modification time on these static files, a lot of browsers (especially FF) have algorithms to guess at how long they should be cached.

Yes, 10 years is overkill. For the most part 1 week will have the same effect. However, it doesn’t hurt if you’re going a bit overboard there.

Basically the only practical reason to use really far away expired headers is marking them as will-never-change for maintainers. Once they see the header they will understand what you did there. Whereas less excessive expiring dates can be less unambiguous.

Shouldn’t your web server deal with that stuff for you?

there are several cache-related filters in JSOS: http://www.servletsuite.com/filters.htm

I think it’s better to put an apache between the client and the container.

Funny, I wrote almost exactly the same filter about a week ago, for exactly the same reason (bad YSlow grade)… :-)

Great usage of asset caching. Helps a lot to read posts that explain things thoroughly.
