hello,

i am using this snippet for user login 

Simple User Login Form example in ASP.Net

it works EXCELLENT !

the only problem i am facing is if user does not login visit the site for day so its auto logout users and if user visit back after two or three days they need to logged in again,

it should work like facebook which nevers logout until user click on logout button pls advice how to make it sure that it always keeps user logged in
