Yes, you can configure the same url to multiple countries redirection.
Go to modules >> modules >> geoip configure >> Select the country and add the url.
For example if you configure the abc.com for US and UK.
When customers from US and UK, they will redirect to abc.com.
I have a doubt, will marketplace extension support other multi-country users too ? Will it affect currency and transaction process?
Can a user purchase different product from various location ? how it will be calculated ?
