Replying with a 301 Moved Permanently
instead of a 404 not found


last update: May 6th 2021 I recently moved my blog to a new host, so several objects don’t exist anymore.

NSA seems to be able to continuously trace our sessions. Next issue was Heartbleed (CVE-2014-0160). SSL renegotiation seemed to be a big issue.
