# urlParsingConfiguration

A property to configure the filter’s parser behavior.

## Declaration

```swift
var urlParsingConfiguration: NEURLFilterManager.ParsingConfiguration { get set }
```

## Discussion

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: 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, this configuration has no effect.
