I am giving an example for my concern. Please assist me on that.
Let’s say I sent my friend a product link of our store. The link is www.A.in/products/tshirt1 few days ago, but we suddenly changed our primary domain to www.A.com (and made www.A.in our secondary domain), so if my friend clicks on www.A.in/products/tshirt1 will he be directed to www.A.com/products/tshirt1 or will he be directed to www.A.com ?
