HttpAllowlist

Setting the policy specifies a list of hostnames or hostname patterns (such as '[*.]example.com') that will not be upgraded to HTTPS and will not show an error interstitial if HTTPS-First Mode is enabled. Organizations can use this policy to maintain access to servers that do not support HTTPS, without needing to disable HTTPS Upgrades and/or HTTPS-First Mode. Supplied hostnames must be canonicalized: Any IDNs must be converted to their A-label format, and all ASCII letters must be lowercase. Blanket host wildcards (i.e., "*" or "[*]") are not allowed. Instead, HTTPS-First Mode and HTTPS Upgrades should be explicitly disabled via their specific policies. Note: This policy does not apply to HSTS upgrades.
