My 2 cents on this: default to the GeoServer ones at the very least, allow
for a different value to be specified for tiles.
Btw, I believe GWC has a way to use eTag values to avoid resending the
tiles, but it's disabled by default and
makes the client do a request to check the eTag anyways?
eTag are a nice solution for tiles that vary often and for which the tile
lifespan cannot be predicted in advance.
