You may want to take a look at

discusses the Last-Modified, Expires, and Cache-Control headers.

I've actually read that document entirely. It indeed says it's dangerous to use etags on dynamic content, but when my data changes its md5-sum is automatically updated, and thus the etag. If I'm missing something here, please point it to me.

This usage message I think is coming from the C side, giving how
the correspoding C function would be called. The error may be
coming from trying to set this for something other than a file on
disc.

I'm using $R->header_out ('Etag', $val) since the other methods do not work. Will Apache consider this value when pondering the meets_conditions predicate?

Also, I hate to whine, but despite the docs saying so, whatever value my script returns is completely ignored; I have to use $R->status (). I'm using Apache::Registry, in case that makes any difference.

Thanks
