Could you try with this php testcase.
http://www.meosource.com/firefox/hits.php

This is the source:
<?PHP
$a = fopen("hits.txt", "r+");

$contents = file_get_contents("hits.txt");
echo $contents;

$contents++;

fwrite($a, $contents);

fclose($a);
?>

I've seen this happening before. View counters updating twice, but I don't see
it with this case.

This is invalid.  <img src=""> means "load current URI as the image" (just like
<link href="" rel="stylesheet"> means "load current URI as the stylesheet), and
since PHP by default disables caching we have to hit the server a second time.

The .htm case is just cached, so doesn't need an extra server hit.
