but you can do a redirect for a new session,
see if the 2nd request carries the cookie,
then do another redirect to the original request. |

我也想到过这样做，不过觉得挺笨的。
有没有更好的解决方法呢？
有没有办法在browser第一次访问我的servlet的时候就知道该Browser是不是支持cookie?
而如果Browser支持cookie的话，上述";jsessionid=956BDE2350B3D6804965F328A3FBB63E
就会在第一次的页面输出中把所有的LINK都encode()上，就是带有：";jsessionid=956BD

But what's the point to start a new session on the *very first*
request? At this point the user has not done anything that needs
to be treated individually.
If you need to deal with a returning user from previous sessions,
then his browser must have cookie support, otherwise there is
no way for you to identify him as a returning user to begin with.

if user bookmarked the url with sessionid, then he can identify him
as a returning user before the session expired.

That's different. Before your session expires, your request is a
*returning* request, not the first one, regardless you came back with
a bookmark or not.
If an app wishes to recognize a returning user with a session id
that has already expired, then it would have to at least persist
this session id somewhere and *keep it forever* because it never
knows when the user is going to come back with that id.
