That's correct, but for todays fast connections the HTTP overhead is higher than the transfer. And if there are many small files to transfer it makes sense to use CSS Sprites.

This is just for the first hit, instead you should set caching headers for static files so they remain on the client.

No, it won't, except the caching headers are set the wrong way. > Don't know if sprites will have an effect or not considering this. I'm right now optimizing our companies homepage using Sprites and it's a lot of work and relatively complex, especially in terms of updates. For RC I don't think it's worth it as there are not too many images and the users are all returning users. For a commercial site where you have not returning visitors or visitors returning after their cache was cleaned it makes sense to spend the time on optimizing with CSS Sprites. Spend your time on new features. Mike -- Michael Baierl <http://mbaierl.com/> - - - - - - - - - - - - - - - - - "Die grofle Mehrzahl unserer Importe kommt von auflerhalb des Landes." George W.
