Expires information being sent by servers is only cache-friendly if the server operator actually spent some time thinking about what the expires value should be. Preconfiguring some Expires default into Apache is worse than useless. It will probably lead to proxy cache operators having to distinguish between a) Expires headers that were configured explicitely by server operators, which can thus be trusted, and b) Expires headers sent by default with the server operators unaware of it, which can thus not be trusted. If the server operator does not configure anything explicitely, then proxy cache operators are in a better position to make up an appropriate default than the Apache group. Koen.
