Why Do Some Sites Start with WWW2?
When you navigate to certain websites, you may have noticed that they start with “www2” instead of just “www”. At first glance, this may seem like a mistake or an error in the website’s URL. However, there is actually a reason why some sites include the “www2” prefix.
The “www” in a website’s address stands for “World Wide Web” and is used to specify a web server that hosts a site’s content. It is a widely used convention that has been around since the early days of the internet. When you type in a site’s URL, your computer sends a request to the specified server to retrieve the web pages and display them on your screen.
So, why do some sites use “www2” instead of just “www”? The answer lies in the technical infrastructure of the internet. In some cases, a website may require multiple servers to handle the traffic and load balancing. When this happens, it’s common practice for a website owner to use a subdomain to distinguish between these servers.
For example, if a website has grown in popularity and its traffic has increased substantially, the website owner may want to use multiple servers to handle the load. In this case, they may use “www1” and “www2” as subdomains to differentiate between the two servers.
Additionally, some websites may use “www2” as a backup server in case the primary server fails or goes down for maintenance. This ensures that the site remains accessible to users, even in the event of a server failure.
It’s important to note that not all websites use the “www2” subdomain, and it is entirely dependent on the website owner’s preference and technical requirements. Some may use other variations such as “test” or “dev” to distinguish between different servers.
