Thanks in advance.

Click the button which sends a request to a servlet which uses session attributes. Then before that servlet sends its response, click the button again. Now you have two threads running the same servlet and using the same session.

To do this your servlet is going to have to run rather slowly, so that you have time to click the button twice.

Also multiple Ajax requests, frames, iframe, and tabs in the same browser.

Just look at how many requests go to make up a modern HTML page - each image, css, js, etc resource is loaded by a separate request, managed "simultaneously" by your browser, and thus "simultaneous" on the server side and each seeing the same session.
