When security cookie times out, redirection does not always occur properly

[TheWitness]

Describe the bug

When using load balancers like Citrix NetScalers in front of Cacti and Basic Authentication, ensure that when the NetScaler cookie expires, that the page is properly reloaded so that the Single Signon Session can be renewed, or the login prompt can be given again.

To Reproduce

Steps to reproduce the behavior:

1. Go to any page

2. Do not click anything until the NetScaler cookie expires

3. Try to click on any other page handled through a callback

4. Not that the page will not change

Expected behavior

Cacti should attempt to be more compatible with these load balancing technologies.
