After the first request comes, the first server is accessed by default. , the second request comes to access the second station, the third request comes to access the third station, the fourth request comes to access the first station, and so on.

- Nginx Chinese domain name configuration example analysis
- nginx Chinese domain name configuration nginx virtual host is bound to a Chinese domain name, such as linuxeye.China, and the browser cannot jump. Why?

All Chinese domain name resolutions need to be converted into punycode codes, and then used by dns Parse punycode code. In fact, all current browsers perfectly support Chinese domain names, but the browser software actively adds Chinese domain name automatic transcoding, and there is no need to re-install the Chinese domain name transcoding control to complete the entire process. The Chinese domain name can be converted into punycode encoding, online transcoding place
