[PHP] Check for page change efficiently [was Re: Creating a blogrolling/link management system]

I doubt most web sites would have a problem with one hit per day :) I am not scraping and redisplaying content...

[PHP] Check for Page
How could I: How could I check to make sure a page exists before I redirect to it (a page within my own server, but page name passed in querystring - therefore it could be changed by client)?

RE: [PHP] Check for Page
Try this:
?
$filename = "dat.txt";
if (file_exists($filename)){
echo "file exists";
} else {
echo "file does not exist";
}
?
