If the supplied argument is greater than 0, it is handled as timestamp
|
|
and will be sent as date of last modification. If it is 0 or omitted,
|
|
the current time will be sent as Last-Modified date. If it's negative,
|
|
it is handled as expiration time in seconds, which means that if the
|
|
requested last modification date is not between the calculated timespan,
|
|
the <literal>Last-Modified</literal> header is updated and the actual body will be sent.
