The problem that Session variables have to overcome is that the HTTP protocol that you use to browse the web is stateless. Each request for a page is completely independant of earlier requests, so if you want to "remember" the variables you have to store that information somewhere. This remembering of user-specific data is called "maintaining state".
Session lives until browser is openned to keep the session relation with the cookie that stores the session ID, if you want to mantain session variables active for a long time, you have to create a cookie, specify the cookie duration, insert your values to the cookie and also check if the cookie exists on every page load. You can save the information in a database as explained here: http://web2py.com/book/default/chapter/04?search=session#session also you have to save a cookie that refers to that register in database, or if you want, you can save the whoke information in the cookie. I dont know any other trick to maintain state with web2py, anybody? 2010/8/5 Cody <[email protected]> > Hello, > > I just started using web2py this summer to create a website. > > Currently, I am having an issue with sessions.
