It’s easy enough to view a list of sites that have cookies in Safari, but if you want to actually see the cookie and parameters used by a particular site, you’ll need to dive a bit deeper into the interface.

In a nutshell:

• Navigate to a web site.
• Select Show Web Inspector from the Develop menu (follow the headline link for instructions on turning on that menu if it doesn’t appear for you).
• Click the Storage tab in the web pane that appears.
• Click the Cookies item on the left side.

Worth taking a minute to give this a try. Kind of fascinating.
