I imagine there's nothing I can do to help get the 2.2 docs updated but if there is, I'm happy to help. > The cache doesn't know the full contents of the response until it's > all been written to the client via the output filters.

I understand the full contents of the item (and its headers) cannot be known until it's cached - but then once cached, everything is known, headers included I believe? This implies items served from cache could have an Etag merged or appended to the already-known headers. Regardless, Apache doesn't offer a way to add an Etag to dynamic content today. Rats. Thanks, Geoff PS. The digest at http://httpd.markmail.org/search/?q=etag shows half a dozen people trying to write custom applications to do this. Now if the HTTP Project takes it on then the world saves untold CPU cycles/bandwidth or maybe even bringing global peace. For that, I'll put up a couple hundred bucks up to see the feature added - anyone on Apace dev reading this, just let me know when it's in trunk and just email me your PayPal info. Or let me know what beer you like - I'm good for a case shipped anywhere in the USA. PPS. BTW Apache rocks. We indorse it publically so keep up the good work! http://www.t1shopper.com/businesspartners.shtml#apache
