JQuery UI Tabs - Cookie Issue

JQuery UI Tabs - Cookie Issue

All,
I am using the JQuery UI tabs plugin with cookies and so far it works
great. I am calling it as under:
$('#container ul').tabs({cookie: {expires:1}});
The issue is, when a user logs out by clicking a logout link, I want
the cookie to get deleted, so when the user logs back in, we have the
first tab selected instead of the last saved tab.
When logged in, when the user clicks the "home" button, I want the
"first tab" to be selected instead of the last saved tab.
I couldn't find anything that does that. Any suggestions ?
Thanks
