I currently have 3 stores online with 3 different domains, running magento with Apache and varnish (using Phoenix page cache extension) running on centos
One store is for uk, another for Ireland and another for USA
Trouble is (Example) If an US user hits the uk store , I would like the user to be notified to go to the correct store on the page, (I do not want them automatically redirected)
I was able to php-pecl-geoip with maxmind database to get this to work, but as users on my website have increased I had to begin using varnish.
how could I implement this functionality on with varnish so I know what country the user is from so I can display a message to the user to view their relevant website?
