Cache improvement request for the “stale-while-ravalidate”

Hi there…
I love this plugin, it’s rocks.

I’m wondering if can make some improvement in the following case:

I have an intranet so all users needs to login so they can access the content.
I did some test with this plugin, enabling the Default caching strategy = Stale While Revalidate.

?While users remains logged-in it’s working very good, it′s great!

But when user logged out and back to login again then having a “Page do not exist” or “Too many redirects” errors.

Can you have some improvement for this?

Thanks in advance!
