Weird Url

Hi all,

I am really lost at how the below url get called in my Yii project

GET http://localhost/myproject/1?_=1369758255887

GET http://localhost/myproject/1?_=1369758256266

GET http://localhost/myproject/1?_=1369758256588

Any idea please ? Look like it attempts to call some scripts in cache or something.

It happens the same to me, always when usgin renderPartial and playing with the last two parameters of it
