there is a broswer,how to keep the same session when i great a new broswer

so please anyone help me

This is a browser function and I don't think that you can change it. In I.E. if you launch a new browser with Control-N, you get the same session. The same may not be true with other browsers. If you launch a new I.E. browser separately (ex. from the desktop icon) it is a separate session. Sessions typically use a cookie that is in memory only and the independent browser window instances don't share that.

One of the few ways I can imagine to make session state work across browser window instances is to use your own session state management that uses a more permenant cookie which IS shared across browser instances.

I just played around with the browsers and found something of interest.

Internet Explorer:
Every launch from it's program icon creates a new windows process. If you launch it once, then hit Control-N, the same process handles the new windows. This is an example of shared in-memory cookies.

FireFox:
BOTH launching it from it's program icon as well as hitting Control-N use the same process. I assume this has to do with the tabbed browser feature of FireFox as well as why FireFox seems to share in-memory cookies (sessions) regardless of how you start a new window.
