Not strictly necessary, as users should be using relative URIs to reference resources on your website. It will, however, let you use absolute URIs to link to subdomains of the domain you post here: i.e. example.com will allow sub.example.com. However, higher up domains will still be excluded: if you set %URI.Host to sub.example.com, example.com will be blocked. Note: This directive overrides %URI.Base because a given page may be on a sub-domain, but you wish HTML Purifier to be more relaxed and allow some of the parent domains too.

'); HTMLPurifier_ConfigSchema::define( 'URI', 'Base', null, 'string/null', 'The base URI is the URI of the document this purified HTML will be inserted into. This information is important if HTML Purifier needs to calculate absolute URIs from relative URIs, such as when %URI.MakeAbsolute is on. You may use a non-absolute URI for this value, but behavior may vary (%URI.MakeAbsolute deals nicely with both absolute and relative paths, but forwards-compatibility is not guaranteed). Warning: If set, the scheme on this URI overrides the one specified by %URI.DefaultScheme. This directive has been available since 2.1.0.
