How are cookies handled right now? Surely the issues should be pretty<br>
much the same?<br>

They are unspecified. From this thread I have learned that Chrome and Firefox start with no cookies. Safari starts with a snapshot of cookies at the point where the user entered private browsing mode. I would not be surprised if Opera or IE8 were subtley different from either of these two approaches.<div class="im">

Option 3 is simple to implement and option 4 would difficult to implement<br>
efficiently. Both would lead to bizarre behavior where data that the<br>
application thought was saved really wasn't.<br>

I certainly can't think of how 3 could ever cause a problem. It<br>
should be the same as the user just logging in from a computer they<br>
haven't used before, shouldn't it?<br>

I strongly share Jonas' concern that we'd tell web applications that we're storing there data when we already know we're going to dump it later. For 3 and 4 both, we're basically lying to the application and therefore the user. Imagine a scenario where a user has no network connection and unknowingly left their browser in private browsing mode. Email, documents, financial transactions, etc could all be "saved" locally then later thrown away before they've had a chance to sync to a server.<div class="im">

I don't think 1, 2, or 5 are good ideas, since they make localStorage<br>
semi-usable at best when privacy mode is enabled.<br>

Apparently Firefox plans to implement #2, and so far I'm standing by WebKit choosing #5 for now. Options 1, 2, and 5 all avoid the problem that 3 and 4 have which is that we're lying about saving data we have no intention to save.<br>
