Gzip Javascript and CSS afeecting Adsense clicks?

Currently i'm trying this code to speed things up a little:
In my .htaccess:

# gzip css, javascript, html file
<IfModule mod_rewrite.c>
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^(.*)(js|css)$ redir.php?file=$1$2&type=$2 [L]
</IfModule>

FileETag None

<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/gif A2592000
ExpiresByType image/jpeg A2592000
ExpiresByType image/png A2592000
ExpiresByType application/x-shockwave-flash A2592000
ExpiresByType text/css A2592000
ExpiresByType application/x-javascript A2592000
</IfModule>

Code (markup):

And the redir.php file:

<?php # this is the file redir.php, to gzip javascript and css
# set the request file name
$file=$_REQUEST['file'];

# Set Expires, cache the file on the browse
# Delete it if you don't want it
header("Expires:".gmdate("D, d M Y H:i:s", time()+15360000)."GMT");
header("Cache-Control: max-age=315360000");

# set the last modified time
$mtime = filemtime($file);
$gmt_mtime = gmdate('D, d M Y H:i:s', $mtime) . ' GMT';
header("Last-Modified:" . $gmt_mtime);

# output a mediatype header
switch ($_REQUEST['type']){
  case 'css':
    header("Content-type: text/css");
    break;
  case 'js' :
    header("Content-type: text/javascript");
}

# GZIP the content
if(extension_loaded('zlib')){ob_start();ob_start('ob_gzhandler');}

# echo the file's contents
echo implode('', file($file));

if(extension_loaded('zlib')){
  ob_end_flush();
  # set header the content's length;
  # header("Content-Length: ".ob_get_length()); # (It doesn't work? )
  ob_end_flush();
}
?>

I kinda got worried since i saw a small gain in clicks after i installed this and thought that it might be 'clicking' the ads on every pageview.
Maybe an expert can shed some light on this?
Thanks in advance.
