How to change the cookie path?

I found out CKFinder will set some cookies like 'CKFinder_Path' and 'CKFinder_Settings' to my browser under path '/'. However these cookies data will be send to my server every time even if the page does not use CKFinder, which cost unnecessary bandwidth. Is any possible to change the cookie path to a sub directory of my domain? It wound be great that I can set it in the config file.
