Google Chrome content settings?

[Rainfall]

Using Google Chrome, I noticed in the content settings there are two options that are very similar:
1. Allow local data to be set for the current session only
and
2.Clear cookies and other site data when I close my browser

What is the difference between them or do they both do the same thing?
Thanks

I do not suggest having any google software on your computer. Google is the largest spying entity on the planet. If you want to use chrome, then use one of these browsers, they are chrome without all the google spyware. Read about, and get them here: (unless you don't care about your privacy)

This one looks exactly like google chrome:

This one looks a little different, but is the same:
http://download.cnet.com/Comodo-Dragon/3...19680.html
If you chose dragon, uncheck the "use comodo secure servers" on install, they will slow the browser down.

The second will clear all the cookies when you close the browser, and the first will disallow any changes to any extensions beyond the page your on. (I think)
