Ajax to refresh query in div, not external page

[MargateSteve]

I have found a fairly generic script for refreshing the content of a div without refreshing the whole page and although it works fine, there are a few things I would like to improve on if they are possible.

<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
 $(document).ready(function() {
 	 $("#refreshdiv").load("activity.php");
   var refreshId = setInterval(function() {
      $("#refreshdiv").load('activity.php?randval='+ Math.random());
   }, 9000);
   $.ajaxSetup({ cache: false });
});
</script>
<div id="refreshdiv">
</div>

There are, in all, 6 divs that I am looking to refresh. 3 of them show on every page and the other 3 are all on the same page (giving a total of 6 on that page) and my 2 questions are.......

1. All of the divs are pulling results from a MySQL db, via Php, and what I have had to do for now is set up a new page for each of the divs content and have them pulled into the requesting page, resulting in 6 new pages.
The main problem with this is that each refresh on each div is counting as a page impression on the hosting company's analytics, meaning we are not getting a true set of page view results.
Is there a way that I can keep the content all on the one page and have Ajax refresh the query/result within the div tags instead of loading/reloading an external page.
I assume that the '.load' section may be the key to this. My guess is that it would be possible to write a function that would do this but am not sure where to start.

2. At the moment, there are 6 different scripts to allow the refresh of 6 different divs. Is there a way to cover all 6 divs in one script? I would assume that I could name all the divs the same but if question 1 is not achievable, then I will still have to call 6 different pages within the script. I would imagine that I could wrap the whole page in a refreshing div but would guess that is not recommended.

Thanks in advance for any help.

A couple questions... How does the hosting company analytic counts a page visit? Does it count via HTTP request or else? Do you have an authority to change the rule of visited page counter?

what if there's a php link include?

Firstly, apologies for not responding to the original reply. I had to reformat my PC and had completely forgotten about this thread until I just got an email notification.

I actually got around the problem I had by setting Google Analytics for the site in question so only the pages I want tracked are being tracked.

However, I would still like to know if there is a way of updating a query via Ajax. The site is for a football(soccer) team and a future plan is to have live updates during a game. Something similar is already done via twitter but they would like to move everything into the site code itself.

Obviously it can be done, once again, via having the query in an internal page pulled into a div but am curious if there is a way to do it without external pages?

Thanks
