Secure sub-domain on a different server?

[aspdaddy]

If I want to have [secure.domain.co.uk...]

and the domain.co.uk is already hosted, do I have to put the secure part on the same server or is there a way to host the subdomain separately.

Thanks.

If you have access to a DNS control panel or DNS manager you can redirect one subdomain to a different server by inputting a new 'A' record.
The DNS control panels I have seen do not specify the protocol http(s) and should redirect both to your new server.
You can then automatically redirect the http:// address to an https:// address using rewrite on the secure server and obviously link directly to the secure subdomain from your main hosted site.
I think this is correct but I welcome corrections.

just to follow this up.

You could then use apache mod rewrite on the secure server to redirect all http requests to https

Wont re-writing or redirecting give the "the certificate does not match" warning to the users?

You should be able to redirect all traffic from http to https using an [R] flag in the .htaccess so that it is visible and the actually address changes.

All your links would point to https anyway but if someone attempted to go to the http version of the subdomain they would be sent back to https
