We have a clients web site which uses a .co.uk domain as the main TLD for the site.
They have another office using a .ie domain and want it to also resolve to their 'uk' web site. At the moment, there isn't a web site behind the .ie domain, but I am sure there must be email services being used for this domain.
We do not host any of the client domains. At the moment, the .co.uk is hosted with a domain hosting company and is 'pointing' via an A-record change to the web site hosted separately from the domain.
It looks as though their .ie domain is with an Irish domain host at the moment.
We are looking for the 'safest' way to have the .ie resolve to the UK web site. The clients prime domain for the web site is .co.uk, so we don't want search engines to somehow recognise the .ie as the main domain and start listing the site using this domain instead of the .co.uk. We also don't really want to do a transfer of the .ie domain as I think this could open a can of worms with the clients email services using this domain. Ideally, we would like the .ie domain to stay where it is to avoid any of these issues.
Can a 301 redirect be implemented with the .ie domain to resolve to the UK web site? If so, who initiates this 301 redirect - can this be done by the .ie web hosting company changing something on the domain setup, by us by altering the HT access file on the web server (would there still have to be a change to the domain setup), or is there another way to achieve the objective?
Obviously, we want to avoid falling foul of any kind of SE penalty.
Hope somebody can help.
