ASP.Net Forms身份验证Cookie跨会话传递

Question

I am fairly new with developing in ASP.Net and I've searched high and low for a resolution to this, to no avail. I am using Forms Authentication to authenticate users and when I login with user A, I abandon the current session, generate a new session cookie/id and redirect from to my content page and everything works as planned. However, when I open a new browser window and navigate to the login screen, thus starting a new session, the authentication cookie for user A is automatically passed to this session and is part of the request cookies collection. Even worse, when I actually log in as user B and get a new authentication cookie then refresh the browser window for session A, it now has the authentication cookie of user B.

I have no idea why this is happening. I thought the browser (IE9) was caching the authentication cookie because the response-header collection is set to cache-control "private" even though I specifically set the Response.Cache.SetCacheability("no-cache") in my code-behind for all pages. Then I was thinking it could be a threading issue.

Any insight into why this is happening is greatly appreciated, Thanks.

Answer 1

Try different Browsers like Chrome and IE. Because browser share same cookie and temp file even opened in new windows. Above scenario will occur if you try with gmail.com or live.com.

Check your web.config files for session settings.
