HKLM\Software\Policies\Google\Chrome
This policy controls how Google Chrome interprets sitelist/greylist policies for the Legacy Browser Support feature. It affects the following policies: BrowserSwitcherUrlList, BrowserSwitcherUrlGreylist, BrowserSwitcherUseIeSitelist, BrowserSwitcherExternalSitelistUrl, and BrowserSwitcherExternalGreylistUrl. If 'Default' (0) or unset, URL matching is less strict. Rules that do not contain "/" look for a substring anywhere in the URL's hostname. Matching the path component of a URL is case-sensitive. If 'IESiteListMode' (1), URL matching is more strict. Rules that do not contain "/" only match at the end of the hostname. They must also be at a domain name boundary. Matching the path component of a URL is case-insensitive. This is more compatible with Microsoft® Internet Explorer® and Microsoft® Edge®. For example, with the rules "example.com" and "acme.com/abc": "http://example.com/", "http://subdomain.example.com/" and "http://acme.com/abc" match regardless of parsing mode. "http://notexample.com/", "http://example.com.invalid.com/", "http://example.comabc/" only match in 'Default' mode. "http://acme.com/ABC" only matches in 'IESiteListMode'.
