Today found in the IE10 in my company's one site, click on other menus, the page will automatically withdraw to the login page, after the check found that IE10 sent out the HTTP headers, and. AUTH cookies are fine, but use the form authentication mechanism (formsauthentication) It is not possible to tell if the user is logged in and the saved session will always be lost.
After verification that this is ASP.net 2.0,3.5 and 4.0 of the bugs, because these versions do not recognize the IE10 user-agent header string, so the user browser version is not recognized, which leads to the ASP.net specific function failure, Think that the browser does not support cookies, do not handle cookies-related code, etc., so that the server does not save the return of the session ID, resulting in loss.
This issue has been officially confirmed by Microsoft, is a IE10 bug, also released two hotfix dedicated to fix this problem, if you encounter the same problem, you can refer to the following instructions:
