Global HTTP Proxy
You can use a Global HTTP Proxy configuration to set a specific global HTTP proxy through which all HTTP traffic for supervised devices will be routed. The Global HTTP Proxy configuration supports either automatic or manual proxies.
Automatic Configuration
If the automatic option is selected (default), in the PAC File URL field you have the option of specifying a URL where a proxy auto-config (PAC) file sits. Devices can retrieve the proxy settings from this file.
Manual Configuration
If the manual option is selected, the you must specify the server address and port for the proxy server. You may also specify a username and password for the chosen proxy server.
