Counter - referrer shows my site. Multiple IP's shown when getting page.

I have a counter with PHP/MySQL/JavaScript on every page. Here is how I call the script:

<script type="text/javascript">
  var refer=escape(document.referrer);
  var dim=screen.width + 'x' + screen.height;
  var pg = window.location.pathname;
  document.write('<img src="/count.php?pg='+pg+'&dim='+dim+'&refer='+refer+'">');
  <img src="/count.php">

For some of my statistics I see the refer being from my site. I looked at the apache logs for the IP's that show this and I see something like this: - - [08/May/2005:09:58:15 -0700] "GET /signup.htm HTTP/1.0" 304 - - - [08/May/2005:09:58:17 -0700] "GET /images/styles.css HTTP/1.0" 200 1195 - - [08/May/2005:09:58:18 -0700] "GET /images/logo.gif HTTP/1.0" 304 - - - [08/May/2005:09:58:18 -0700] "GET /images/bg.gif HTTP/1.0" 200 85 - - [08/May/2005:09:58:18 -0700] "GET /images/verification_seal.gif HTTP/1.1" 304 - - - [08/May/2005:09:58:18 -0700] "GET /images/shadow.gif HTTP/1.0" 304 - - - [08/May/2005:09:58:19 -0700] "GET /images/dot.gif HTTP/1.0" 304 - - - [08/May/2005:09:58:19 -0700] "GET /images/horizontal_solution_PP.gif HTTP/1.0" 304 - - - [08/May/2005:09:58:19 -0700] "GET /count.php?pg=/signup.htm&dim=1024x768&refer=http%3A// - - [08/May/2005:09:59:03 -0700] "GET /demo.htm HTTP/1.0" 200 7385 - - [08/May/2005:09:59:05 -0700] "GET /count.php?pg=/demo.htm&dim=1024x768&refer=http%3A// HTTP/1.0" 200 35 - - [08/May/2005:09:59:23 -0700] "GET /stats.php HTTP/1.0" 200 10289 - - [08/May/2005:09:59:24 -0700] "GET /count.php?pg=/stats.php&dim=1024x768&refer=http%3A// HTTP/1.0" 200 35 - - [08/May/2005:09:59:38 -0700] "GET /tutorials/ HTTP/1.0" 200 11048 - - [08/May/2005:09:59:39 -0700] "GET /count.php?pg=/tutorials/&dim=1024x768&refer=http%3A// HTTP/1.1" 200 35

These all appear to be from the same user, but they have different IP's. You'll notice that at the exact same second 4 of the images of the page were requested but they say they're from different IP's.

Any ideas how to fix it to not get duplicate entries that say they came from my site?
Who is Participating?

You are geting this because the user is sitting behind a proxy server. The proxy server makes a request for the page then it grabs all the image links and passes those links to other proxy servers in their server farm, and they come and grab the images to add to their proxy cache just in case another user visits your page via their proxy server, they do this to save badwidth and have pages load faster by storing the images in thier cache!


Just another good reason to hate AOL9s) way of doing things!


what is the url of the page that this script is one?

The PHP script for the counter is /count.php and the javascript is on every page of the site that calls it as an image. Is that what you're asking?

Thanks for the explanation. That makes sense.

Now what should I do to fix it?
A little BTW comment on this... when I last checked AOL during a development process, I found that the images from my website, as well as being cached had also been converted to a proprietary AOL file format, presumably so that they could be 'compressed further'. I think their file format is called PIC. Interesting that they would go to all that bother, isn't it. Brings to mind possible intellectual property/copyright issues too, a la Google Images.

Now that we know what is causing the problem, how do we fix it?

Any ideas how I can get the php counter to check for this?
