网站启用CDN前，如何进行测试？

如果您购买了CDN服务，正式使用前希望在不修改域名解析的情况下进行测试，我们推荐您使用域名绑定host的方式。
步骤一. 获取CDN服务的边缘节点IP
在控制台上找到加速域名对应的CDN域名

ping 该CDN域名，获得边缘节点IP

步骤二. 绑定host
windows 环境下
在C:WindowsSystem32driversetc目录下打开hosts文件，按下图样式填写步骤1获得的边缘节点IP和加速域名，并保存。此处以1.1.1.1 和 www.utestcdn.cn 为例

#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host
# localhost name resolution is handled within DNS itself.
#       127.0.0.1       localhost
#       ::1             localhost

1.1.1.1 www.utestcdn.cn
完成后，ping域名 www.utestcdn.cn，解析指向ip就是1.1.1.1了。
上述步骤完成后使用浏览器进行测试
