Start with a local question. Keep the network, language, and delivery settings separate so the result tells you something useful.
German text does not identify an Austrian storefront
An Austria proxy test should record the selected market as well as the page language. A German-language product page may serve several countries. Check the market selector, delivery destination, and checkout summary before labeling a capture as an Austrian offer.
Follow a Vienna-to-Graz delivery comparison
Use the same product and quantity with delivery examples in Vienna and Graz. Record availability and shipping choices at the same checkout stage. This Austria scenario tests the application's address logic while the network stays fixed; it makes no claim about selecting either city's IPs.
Compare Austria and Germany one variable at a time
For cross-border retail research, retain the Austrian address while changing only the exit, then repeat with a German address. Keep those two comparisons separate. You can then tell whether a redirect or offer change follows the network country or the customer-selected market.
