问题 Can someone tell me why the session vars are not passing between pages? They were working up to 2 days ago. Now its not? There is a third party system that logs users in based on the third party system. I direct users to the login page with the return url.

问题 I'm using VS2010 and created a simple asp. web forms application, using Development Server to test it. I try to store user data - queried from sql server - in the session, since I don't want to access database in every request.

阅读更多关于 Sharing SESSION Variables Between Multiple Subdomains

I have a website www.example.com. That will have multiple subdomains that work with a single application or program. For an example, login.example.com will allow the user to log in to the site while system.example.com will allow the user to access an information system, while forums.example.com will allow the user to access forums. We may need to pass information between the subdomains such as a user id, or a user preference, etc. How do we go about passing information between the sudomains using SESSION variables? EDIT: I like this idea: As the first thing in your script: ini_set('session

阅读更多关于 MySQL wait_timeout Variable - GLOBAL vs SESSION

问题 SHOW VARIABLES LIKE "%wait%" Result: 28800 SET @@GLOBAL.wait_timeout=300 SHOW GLOBAL VARIABLES LIKE "%wait%" Result: 300 SHOW SESSION VARIABLES LIKE "%wait%" Result:28800 I am confused by the results. Why does the last query give Result:28800 ? 回答1: Your session status are set once you start a session, and by default, take the current GLOBAL value. If you disconnected after you did SET @@GLOBAL.wait_timeout=300 , then subsequently reconnected, you'd see SHOW SESSION VARIABLES LIKE "%wait%";

问题 Okay, so first off before anyone attempts to make a determination that this is a "duplicate" question; I have reviewed most of the posts on SO regarding similar questions but even in combination of all that has been said I still am somewhat at a dilemma as to the definitive or maybe I should say unanimous agreement on this. I can however say that I have (based on the posts) conclusively determined that the answer is based on the scope of the requirement. But even with consideration of this,
