Redirect loop when returning to dCacheView with problematic certificate

[alrossi]

I have been having trouble with my X509 for some reason ... seems that there is a CRL issue which I'm trying to get to the bottom of. But I can reproduce the redirect loop behavior as follows:

1. go to https://:3880 (dCacheView) [here it refuses to authenticate me because of this certificate problem, and shoves me over to the login page]. I log in.
2. Now go to https://:3880 /api/v1. I'm asked to log in again. I log in again.
3. Now try to go back to https://:3880 (back button or put the URL into the navigation bar). That is when it goes into this infinite loop.

Closing the tab and reconnecting fixes the issue.
