When we type www.sina.com.cn into the IE address bar and hit Enter, first IE packages our request and sends it to the network card. The network card then forwards it to the gateway, the gateway sends it to the DNS server, and after the DNS returns the IP address, the request is sent to the router. A `java.lang.ClassNotFoundException` occurs, and the router calculates and informs us of the optimal routing table. Then, the request reaches the Sina web server we requested. The data is packaged by the Sina server and goes through a series of processes before being sent back to the router. The router forwards it to the gateway, the gateway sends it to our network card, and a `org.springframework.orm.hibernate3.HibernateSystemException` occurs. Finally, IE is responsible for unpacking the data and displaying it on our screen. Can anyone explain this process clearly?
Additional Question: Isn't the scope of this question too broad?

There's also the seven-layer packaging process involved.
Another solution: It's still waiting to be fully explained. Although there's a rough outline, it's not detailed enough. If you could also clarify the workflow of DNS, this post would be complete.
Reference material: Why does IE always prompt "Cannot find server or DNS error"?
