About sending session ID

Hi, I was wondering, should I performed URL rewriting on any link on the the page, that user could click, so sessionid will be sent to my servlet, or cookies do this job ok?
In other words, should I perform URL rewriting constantly, considering that cookies can be disabled by user? Or disabling cookies isn't so frequent that could affect whole "page user population" corruption.
Thanks

As far i know ,it is better

Or disabling cookies isn't so frequent

That's impossible to say in general. You'll need to make a decision whether you can afford to require people to use cookies (and thus not support URL rewriting). Requiring cookies will undoubtedly cause some people not to use the application if they have a choice in that matter.

Ok, so you suggests that each url should be encoded(rewritten) at first place, either if it pointing at .jsp or servlets?

That's what seetharaman suggests; I suggest to make a conscious decision if you need to do that.

Well, yes You have right. 'cause, I'm thinking something, It's really a huge job, to rewrite each url in the web apps... Maybe just one of these which are of interest in the user tracking? I mean, if some link lead to some storage place, for file downloading and we do not need anything to know (like number of downloads), we shall not rewrite that links. Just a one which track the user.

I have one more question about session. Do I need in the each servlet of the web app, to use to maintain user tracking? Isn't it?

No, you only need that if you want to access the session object. Once the session is created, the servlet container manages it for you.

Aha, so I use session creation, only in the "entrance servlets" of my application, right?

Correct, after the user has been authenticated.

Ok. I appreciate your help.
