问题 I am currently using window.sessionStorage to store a uniquely generated session ID. This ID is passed to all ajax calls to the server and persists across page navigation and reloads. This seems to work perfectly for my target browsers, with one caveat: the duplicate tab functionality in Chrome. Duplicating the tab copies the session storage to the new tab. When the new tab loads and communicates with the server, it now has the same "unique" identifier as the duplicated target tab. Are there

问题 I am wondering if there is an existing trick to filter on the cookies. I need to get the session cookies only and to discard the other. The usual way to read cookies using Javascript is: document.cookie However this prints all the cookies, my goal here is to get the session cookies only. I know that unlike "normal" cookies a session cookie has an expiration date. Does anyone have a code sample to achieve this session cookies extraction?

问题 I have a mysql table with userid, usernames and passwords and if the given password matches with the given username I create 3 cookies: userid username userpassword (md5) - I create this because I recheck the password and the username from the cookies when the user saves important settings (without asking the user to complete forms).

问题 I'm trying to help a friend - they have a pretty big web application (ASP.NET 4.0, Visual Basic) that has a number of subfolders that all act as quasi sub-applications (but they're just subfolders of the main application). This application will be split up into multiple independent web application because in its current form it's hard to maintain and develop any further. The problem is that the current monolithic application uses a number of session variables for things like user information
