For PHP/3: php3_last_modified: on/off
Others should be configurable via mod_header using the Header directive.
Of course, this all depends also on some other stuff.. server-parsed HTML
and CGI generated HTML may depend on other files than their own, i.e. you
need a time-stamp out of a database _and_ the modification date of the
servlet that does the action, so a server configuration option might output
junk and result in erroneous cacheing of the page (i.e. the server returns
the last_modified for the servlet but not for the data it outputs -> proxy
caches might then return an old version of this page).
If using server-side applications, the last_modified header should therefore
be returned by the application and not by the server.
