that would result in *way* too many HTTP requests dude ;)

i'm thinking i evaluate what URL is called up in PHP, figure out what cache
files are needed (i now use multiple stages of cache files for some stuff
like the main HTML template), and output a new "master cache file" that is
a file that gets called up rather quickly with readfile() after a
file_exists(translateURLtoFilesystempath($untranslatedContentURL)) to see
if regeneration for any particular URL is needed..

public function translateURLtoFilesystempath ($url) {
            $r = $url;
            $r = str_replace('/','---',$r);
            $r = str_replace('?','-_-',$r);
            $r = str_replace('&','__-',$r);
            $r = str_replace('=','___',$r);
            return '--_'.$r;
}
public function translateFilesystempathToURL ($path) {
            $r = preg_replace ('#.*--_#', '', $path);
            $r = str_replace('---','/',$r);
            $r = str_replace('-_-','?',$r);
            $r = str_replace('__-','&',$r);
            $r = str_replace('___','=',$r);
            return $r;
}

yea, that's the C++ attitude ;) you do know C++ got dinosaured for a *more
simple and intuitive* C# right? ;)
