can someone point me to the class/logic where each visit gets associated with the visit ID and therefore also the check for an existent cookie (to identify returning visitors) lives?
I’d like to extend this logic and in my case there are several reasons I cannot do it on the application I’m monitoring with Piwik and send the UID as parameter.
Should I expect any obstacles when extending this logic as plugin? (In that case I’d probably try it quick and dirty by modifying the core file - the extension I have in mind should be quite simple/short.)
Thanks for tips!
