# urlParsingConfiguration A property to configure the filter’s parser behavior. ``` var urlParsingConfiguration: NEURLFilterManager.ParsingConfiguration { get set } ``` ## Discussion Use this property to control which URL components to exclude, and to customize parsing behavior during sub-URL enumeration. This determines how the filter parses URLs which sub-URLs it generates for matching against the filter data set. For any excluded component – domain, path, query, or fragment – the filter substitutes `"%*"` in place as a placeholder. By contrast, if you strip the domain or `www` subdomain, they’re removed entirely without a placeholder, since URL matching doesn’t typically require them. As an example, consider the URL `https://www.example.com/a/b/c?id=123#fragment` and a configuration set as follows: ```swift var config = manager.urlParsingConfiguration config.excludeScheme = true config.domain.stripWWW = true config.path.excluded = true manager.urlParsingConfiguration = config ``` The parsing result is `example.com/%*?id=123#fragment`, where `"%*"` acts as the placeholder for the excluded path component. The presence of a placeholder indicates the original URL contained that component, but the parsing configuration excluded it. If the filter manager sets [`urlParsingRegularExpression`](/documentation/NetworkExtension/NEURLFilterManager/urlParsingRegularExpression), this configuration has no effect. --- Copyright © 2026 Apple Inc.
