</span>I think unbound cookies are an incredibly vulnerable session token. I don't know enough about the security implications of HTML Local Storage, so it's possible that using that for session storage could obviate some of the threats, but I think that would depend on other factors, such as whether the container session was bound or not.<br>
<br>
I can only speak for myself, but "inconvenience" would not come anywhere near my threshold for unbinding them, and I'm pretty sure my security people would back that view.<br>
<br>
It's fair to say that the problems with logout might change that view, but since I think the typical result for logout is going to be failure anyway, it doesn't seem like enough of an argument to me.<br></blockquote><div><div class="gmail_default" style="font-family:courier new,monospace;display:inline">Thanks, so it does have a real security implication is what you're saying. (I'm not sure if I'll need details but it impacts security significantly is a viable answer.)</div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
