Hello Danny.

Actually, that looks like 8 cookies from what I can tell. If you can use a browser extension to view the cookies sent for a page it may show you the domains associated with those cookies. (I use and recommend Chris Pederick's excellent Web Developer extension for Firefox).

I agree with my anonymous brother that most or all of these have nothing to do with PerlMonks per se and if you use WWW::Mechanize to access the site (for whatever reason) they could safely be ignored.
