I have seen on the web some domain names having prefix of ww2 or ww3 or so (ww2.somedomain.com, ww3.yourdomain.com). And these happen mostly when travelling from a page to page. What would be the reason of having such subdomains? Is there anything special about them or are they just another sub domain? I mean, are they useful in any particular context?
Was just curious to know. Thanks.
People running large(-ish) sites used to do this when they needed to break up the load between more than one server. One machine would be called
www then the next one would be called
Today, much better load balancing solutions are available that don't require you to expose your internal machine naming conventions to the browser clients.
