I know that session sends the cookie in order to recognize the user the next request he attempts. What happens exactly when I make a CTRL-N at Internet Explorer for example.. or open another IE window, or another type of Browser? is the cookie the same??
the behavior is totally dependent on the browser. From what I understand: if you open another IE window by double clicking on the icon -- that window will have a DIFFERENT session from the other. If you open another IE window by hitting Ctrl+N of File|New they will SHARE session. For other browsers such as Opera and Netscape -- no matter how you open the other windows, you will still SHARE session between the windows.
