• The Agent Desktop is itself loaded over HTTPS, so a production widget script URL has to be HTTPS. Only a localhost URL on the developer's own machine escapes mixed-content blocking. A plain-HTTP script URL, like the one HTTP CDN example in Cisco's layout article, therefore only works against localhost. inferred in context
• Content loaded from loopback addresses such as http://localhost or http://127.0.0.1 counts as coming from a secure origin, so it is not blocked as mixed content. in context
• Browsers block scripts requested over HTTP from a page loaded over HTTPS, because script src is blockable mixed content. in context
