Although I understand almost nothing about this subject I was reading about the Protocols and Safety Certificates, because I saw this alert Mixed Content on a website
Reading about it I came across terms like "Mixed Content", "Optionally Lockable Content" and "Lockable Content" and wondered what they were...
- What defines a document as "Mixed Content"?
- What are the "Content optionally lockable" and whether they are optional as I define that they are allowed or should be blocked?
- And what are the "Lockable content"?
My intention is to know what I can or cannot index on my site as CDNs, imagens external, etc., and whether they are "Content optionally lockable" and how I define whether on my site they are allowed or not.
