Block access to a list of URLs

This policy prevents the user from loading web pages from blacklisted URLs. The blacklist provides a list of URL patterns that specify which URLs will be blacklisted.

A URL pattern has to be formatted according to https://www.chromium.org/administrators/url-blacklist-filter-format.

Exceptions can be defined in the URL whitelist policy. These policies are limited to 1000 entries; subsequent entries will be ignored.

Note that it is not recommended to block internal 'chrome://*' URLs since this may lead to unexpected errors.

From M73 you can block 'javascript://*' URLs. However, it affects only JavaScript typed in address bar (or, for example, bookmarklets). Note that in-page JavaScript URLs, as long as dynamically loaded data, are not subject to this policy. For example, if you block 'example.com/abc', page 'example.com' will still be able to load 'example.com/abc' via XMLHTTPRequest.

If this policy is not set no URL will be blacklisted in the browser.

Example value:

example.com
https://ssl.server.com
hosting.com/bad_path
https://server:8080/path
.exact.hostname.com
file://*
custom_scheme:*
*

Supported on: At least Microsoft Windows 7 or Windows Server 2008 family
