JavaScriptOptimizerAllowedForSites

Allow JavaScript optimization on these sites

Supported on:

  • Chrome (Windows) since version 133

Description:

Allows you to set a list of site url patterns that specify sites for which
advanced JavaScript optimizations are enabled.

Wildcards, *, are allowed.

JavaScript optimization 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 JavaScriptOptimizerAllowedForSites policy but site-one.com loads a frame containing site-two.com then site-one.com will have JavaScript optimizations
enabled, but site-two.com will use the policy from DefaultJavaScriptOptimizerSetting, if set, or default to JavaScript
optimizations enabled. Blocklist entries have higher priority than allowlist
entries, which in turn have higher priority than the configured default value.

If this policy is not set for a site then the policy from DefaultJavaScriptOptimizerSetting applies to the site, if set, otherwise
Javascript optimization is enabled for the site.

Supported features:

  • Applied to browser without restart. Note that some ongoing tasks may not be affected.
  • Applied at Samsung Browser profile level.
