Proxy settings
Script Custom Actions support proxy configuration to allow virtual machines without direct internet access to connect to the internet through a proxy server.
To configure proxy server for a Script Custom Action, specify the Http Proxy and Https Proxy parameters
in the Advanced Action Settings tab in the plan action view.
To bypass the proxy server for specific traffic, use the No Proxy parameter to define a comma-separated list of
domains or IP addresses.
An example scenario in which it might prove useful is when a script calls the cloud metadata endpoint (169.254.169.254).
Only the Script action's process traffic is routed through the proxy server; the rest of the virtual machine's traffic is not affected.
Parameters format: <http or https>://<proxy server URL>:<port>
Examples: http://proxy.example.com:8080, https://10.0.0.42:3128
