Single Page Application: page reload

Question

I've simple SPA and I make log out on reloading. As I understand the disadvantage of NOT logging out on reloading is to reinitialization of the whole application.

Questions:

1. What are the disadvantages of NOT logging off at Single Page Application?
2. What is the best way to achive NOT loging of on reloading (F5)?

Answer 1

1. The advantage is that not logging off will avoid pissing off your users so much that they'll want to kill you :-). Seriously, if an application logged me off every time I refresh a page (or open a link in a new tab), I would never use that application again.

2. Well, don't do it. Make sure the authentication token is stored in a place surviving a refresh, i.e. not in some JS variable, but in a cookie or local storage, for example.
