Hello,

I hope I'm not too out-of-topic, but I have a little question about
Ada Web Server: how can I send "304 Not Modified" responses on requests
for contents generated by AWS client (i.e. not files), using
Last-Modified/If-Modified-Since and/or Etag/If-None-Match HTTP headers?

I see that when responding with a File, AWS automatically generates
Last-Modified and respond 304 to appropriate If-Modified-Since
conditional requests; But I haven't seen any way of doing the same thing
on generated content.

While I didn't really expected everything to be handled for me, I'm
really surprised by not finding anything to add custom headers to HTTP
responses.

Am I missing something or is it really impossible?


Thanks for your help,
Natasha
