Why Hai Phong matters for localization testing
Hai Phong brings its own quirks. Sites there personalise pricing, stock and even page layout by visitor origin, so a request from a foreign datacenter IP describes a market that doesn't really exist. Only in-country addresses reveal what a genuine local user sees — which is exactly why localization testing needs local exits here.
Best proxy type for localization testing
The proxy type that fits localization testing best is Residential Proxies, paired with sticky sessions. It balances success rate against cost for this exact use case; you can fall back to datacenter for easy targets, but the hard ones in Hai Phong, Vietnam demand residential-grade trust.
