I don't like accepting cookies while browsing so use Firefox and ask to be prompted when a site tries to save a cookie. One very persistent one, which I can't find anything about, is srv-date-increment-parsley.config.com.
I just got that request while updating this page. How is that possible? What the heck is it and why hasn't anyone posted anything about it? How can it increment a number in the cookie that it's trying to save on my pc - if it hasn't saved a cookie? I don't understand it all but this is very annoying.
