Hide AJAX info from Firebug, how? (with a working example site)
OK, I know this question has been asked so many times.  
 
But there's this website developed with AJAX (not with jQuery/MooTools/...), which hides AJAX info COMPLETELY from Firebug console (except for some cookies).  

It is in Chinese, the official blog of a social network website.
Mostly you guys can't read it, just click on the menu and pay attention to the console.

Here it goes..

I'm wondering how they did that?  
Does anyone have a clue?
