A better version

Can't Post

I have this script I've been working on that can be - in theory - embedded in an xssi call that recognizes the DOCUMENT_URI, queries that against a flatfile list and increases a count for that particular line. That all works fine in testing, but I am wondering a few things....
How would this thing handle simultaneous access? Does it need flock, and if so, where do I stick it?
As is, if the uri is equal to a stored variable of URL in the flatfile (multi-line, multi-entry) it increases the count, if not the only way I could get it to work without wiping the flatfile was by adding an else statement that does a print DATA $line;.
Does that mean that each time the uri does not equal the $url that it is rewriting the entire file over again?
Basically, I am interested in how to make this a better application, and about the flocking whole thing...
Any help would be apreciated, and here is the code so far:
#open and read data file
open(DATA,"$datafile");
@lines = <DATA>;
close(DATA);
#start counting
open(DATA,">$datafile");
foreach $line (@lines) {
($count, $section, $month, $year, $url, $title, $description) = split(/\|/,$line);
if ($ENV{'DOCUMENT_URI'} eq $url) {
$count++;
print DATA ("$count|$section|$month|$year|$url|$title|$description");
}
else {
print DATA $line;
}
}
