Sure, an interesting project for web app development is Webware.

Cookies can be a convenient way of letting your webapp know which user is making that particular HTTP request.  Another way to do it is to embed an identification string into the URI of all hyperlinks in your webapp.  I would be surprised if webware did not provide a mechanism for automatically generating these kinds of URIs.

You should read more about how cookies work, you can limit the lifetime of a cookie to only last as long as the current session (until the user quits the browser instance):

Hopefully the above will help answer some questions about cookies in web application development.
