I agree. That would be absurd.
However, I don’t like not having the option of using HTTP if I want to use it. It’s okay if the webserver redirects me, but I don’t like if my browser does it when I didn’t tell it to. I might want this when doing development, port tunneling, VPN stuff, etc. In most cases, it won’t matter, but when it does, it will be a pain in the ass.
If this is expected and everything is peachy, then why does Instacart say to not give the receipt to the customer? You don’t see this as something to hide?
