Subject: [PATCH 3/3] implement http not modified
On each request send "last-modified" header with the modification time of
each file. the client will store this field and send it on the next
request(s). On the server check the "if-modified-since" field with the
modified date sent by the client, depending on this send all the data or
the "304 not modified" http status.
CAVEAT: it is assumed the exact field will be send by the client, no date/time
conversion is done for simplicity sake, as far as that's possible with http ;)
