WebRTC IP Handling Policy for URL Patterns

Controls which IP addresses and network interfaces WebRTC can use
when establishing connections for specific URL patterns.

How It Works:
Accepts a list of URL patterns, each paired with a handling type.
WebRTC evaluates patterns sequentially; the first match determines the handling type.
If no match is found, WebRTC defaults to the WebRtcLocalhostIpHandling WebRtcLocalhostIpHandling. policy.
This policy applies only to origins—URL path components are ignored.
Wildcards (*) are supported in URL patterns.

Supported Handling Values:
default – Uses all available network interfaces.
default_public_and_private_interfaces – WebRTC uses all public and private interfaces.
default_public_interface_only – WebRTC uses only public interfaces.
disable_non_proxied_udp – WebRTC uses UDP SOCKS proxying or falls back to TCP proxying.
