Description

Allows you to set a list of site url patterns that specify sites which are allowed to run JavaScript with JIT (Just In Time) compiler enabled. For detailed information on valid site url patterns, please see https://chromeenterprise.google/policies/url-patterns. Wildcards, *, are allowed. JavaScript JIT policy exceptions will only be enforced at a site granularity (eTLD+1). A policy set for only subdomain.site.com will not correctly apply to site.com or subdomain.site.com since they both resolve to the same eTLD+1 (site.com) for which there is no policy. In this case, policy must be set on site.com to apply correctly for both site.com and subdomain.site.com. This policy applies on a frame-by-frame basis and not based on top level origin url alone, so e.g. if site-one.com is listed in the JavaScriptJitAllowedForSites policy but site-one.com loads a frame containing site-two.com then site-one.com will have JavaScript JIT enabled, but site-two.com will use the policy from DefaultJavaScriptJitSetting, if set, or default to JavaScript JIT enabled. If this policy is not set for a site then the policy from DefaultJavaScriptJitSetting applies to the site, if set, otherwise Javascript JIT is enabled for the site. Example value: [*.]example.edu

What to embed
Theme

Adds one script line: the theme follows your site’s appearance and the height fits the content. If your site blocks scripts, the embed follows the visitor’s system theme.
