How can I change all links in the store to be https if the site accessed via https?

I did not want to switch the entire site to SSL.

This is something that many of us don't want.

Unfortunately, this is no longer really our choice - Google is demanding 'SSL everywhere' - and although I object to being dictated to in this manner (and our business can survive without Google), most ecommerce sites can't - So to survive - the future of eCommerce is 'SSL everywhere' regardless of what you and I want.

All I was looking for was for the http://domain/ to have all http:// links, but if arrived at the site via https://domain/ for all links to follow the same and be https:// links. Is that possible? If they were relative links, they would inherit the protocol, would they not?

Yes, it is possible, and yes you are correct about inheriting the protocol - but as I just wrote in a previous post, the security implications of this inheritance are huge.

mc1-8 has suggested how it would be possible (at least in theory) to do what you are seeking, with very little effort or changes, but if this is something that you would like to achieve *without* those risks, things become a lot more difficult. I *know* that this *should* be possible (without the risks). I've even had a few ideas how to make it so, but for each idea I've had so far, a little more thinking has me rejecting the approach as being unworkable for one reason or another. The more I think on it, the more complex the solution becomes (perhaps I'm over thinking it?)

Anyway, possible or not, easy or difficult, as I stated, we don't really have much of a choice these days - it's going to be 'SSL everywhere' - or a store that can't be found, and if it could be found, the warnings about 'insecure' is a nail in the coffin anyway.

Sorry to say, but IMO, you should give up on this idea, bite the bullet (as I have done), and do what Google is demanding us do (even if it is only for the benefit of Google, 'cos they sure aren't doing it for *our* safety).
