It appears to be consistantly giving me a secure connection now which is good. Having said this, if I navigate away to my home page (set to Startpage the search engine) and then do a search for amiga forums and select the amiga.org link, the link is still the non-secure one (expected I suppose at the moment) and selecting it navigates to it but on the non-secure http:// not the https://...yet it still leaves me logged in. Whether that is normal or not I don't know.
Other secure sites I have tried re-direct to https:// if a non-secure URL is specified. Again, I don't know what is usual or normal here in this case, but I can now get a consistent secure connection so I am happy about that, thank you.
