I added the following HTML to the head section of my blogger.com theme.

But when I view a page via HTTP the browser tells me I am requesting insecure HTTP resources from a second HTTPS page.
https://mrpmorris.blogspot.co.uk/2017/06/loading-assembly-from-specific-path.html
If I right-click the alexgorbatchev link in the Chome Console and select Open in new link it takes me to an insecure page, if I add https:// to the start of the url it loads securely.
Why are Chrome and MS Edge trying to fetch these resources via http when the markup explicitly indicates https?
$ curl -I https://alexgorbatchev.com/pub/sh/current/scripts/shBrushPerl.js -k
HTTP/1.1 302 Moved Temporarily

Location: http://agorbatchev.typepad.com/pub/sh/3_0_83/scripts/shBrushPerl.js

You can see that it's actually being redirected to TypePad.com. There's a "cool" story behind this. Back in the dark days when bandwidth was expensive, I was getting 100s of GBs of traffic on these scripts, which was starting to cost over $100 a month. I moved the files to free hosting service, but I didn't want all existing links to alexgorbatchev.com to break, and so I set up redirects.
I should probably fix the redirect to use the same protocol as the request :)
