@SpectreReturnsFeb 13.2006 — #What exactly do you want to know? I believe that either date() or time() examples at php.net provide a way of checking the last modified timestamp in a file.
@bokehFeb 13.2006 — #Since a URL is not a file but in fact a source of data it is not possible to put an age on "[I]the file[/I]". If on the other hand you want to when a file was last modified you can use [I]filemtime()[/I].
@SpectreReturnsFeb 13.2006 — #You could probably tweak your apache so that it'd serve the last modified dates as headers (or maybe it already does this), and then open a socket to there, and rip out the headers for it. Of course, this'll only be useful on your own server, unless it does indeed already do it.
@bokehFeb 13.2006 — #serve the last modified dates as headers [/QUOTE]It is true that apache could be configured to output that header but unless it is a completely static file the header is meaningless. A php file could remain unchanged for year yet be serving different data on every single request.
