New ClickThru URL Format?

[himalayaswater]

I saw new click thru url format on one my site (I'm not special adsense member) as follows (note DELL and HP are just generic name but they are using product name)

javascript:_ADS_ClickDestinationUrl(DELL_banner_link);
javascript:_ADS_ClickDestinationUrl(HP_banner_link);

Also, ad code ejecting lots of new javascript in frame such as browser detection and some call back and stuff like that. Here is how it ended

BrowserDetect.init();
</script>
</div><script><!--
_TriggerEvent("domload");// -->
</script>

There is also comment left in javascript as follows:

/* *********************************************
This code came from [quirksmode.org...]
In order for this to function properly, it must be updated regularly
***********************************************/

Has any one noticed anything new in their site or account (except from low CTR and eCPM )? Look like this is new tracking system to me or may be some new changes coming to adsense like:

1. More ad control
2. Ad group control
3. Powerful Ad filtering
4. ?

That's plain old browser detection which was used by some of us years ago when there were incompatibilities between browsers.

If the visitor's browser was IE then you served up the IE version, if Netscape, then the Netscape version etc.

Content was always the same, just a way to overcome browser conflicts so your pages theoretically looked the same to everybody.
