php - How can Google Analytic Cookies appear without using Analytics? -
i have never used google analytics on web site.
i have implemented online booking system wrote using javascript , php.
my php code includes "trace" logs data , events related application. there separate trace log each user session. trace includes list of cookies , values available.
i have discovered single instance cookies named utma, utmb, utmz, ld893_bl , utmc present in user session. found utm.. cookies belong google analytics. (still no idea ld903_bl cookie is.)
my question this:
since web page includes javascript, , code not set these cookies, how can cookies exist domain?
