Web App Session Recover Data

If any way to recover data on the browser using like session id when server disconnect

Not reallly. Typically it’s not the server that disconnects though. Usually it’s a network issue somewhere in between. Your best bet is to send the user back to a login screen or dashboard.

what is it that you are trying to do?

ok
the user go back to main page but it lost the data on the listbox

Then use a cookie to track the user and store the session “state” in a database using that cookie. When they return, look it up and restore their state.

Be very careful with cookies though. There are very strict usage rules in the EU.

You could just use a user login too, and store information based on their account.
