asp.net - Managing Sessions across Tabs -

i have 2 apps(say app , app b). app gives link navigate app b. on initial load of app b, creates session new new session id. farther moving app, more values stored in session. if select link , "open in new tab" multiple times, create new guid session id in each tab. close tabs , come app a. app doesn't have session management mechanism , session never expires app b has , has session expire page.

after leaving browser idle sometime, 20 mins or when seek navigate app b, detects expired session browsers cache , straight redirects session expire page of app b not expected behavior. every time user tries go app b, should have fresh session.

any suggestions on how handle scenario ?

thanks in advance!!
