Well a reliable source tells me that there is no w3c spec for Cookies, and 
infact the concept was conjured by Netscape. There is an RFC spec for 
Cookies, but it's largely ignored.

So as the useful browsers out there ignore Cookie requests without a path, it 
might be handy to add it by default so other people don't spend an hour or 
two sitting there thinking "Why doesn't this work?". The current context path 
would be handy, so the response code could look like this:

public void addCookie(Cookie c)
{
	// whatever
	if (c.getPath() == null)
		c.setPath(getContextPath());
	// etc
}

Just a thought :)
