# URL Content Filter

**Trigger**: Use when implementing URL categorization, content filtering, or parental controls.

**Libraries**: `url` (parsing), `reqwest` (category lookups), `regex`, `adblock-rust`

**Implementation**: URL categorization via domain suffix/prefix matching against category databases (adult, gambling, social, streaming, etc.). Keyword-based content filtering in URL paths. Referer-based filtering. Category overrides per client/group. Integration with DNS blocking and HTTP inspector. Category DB update via automated feeds.

**Connected**: `http-https-inspector`, `dns-adblock-engine`, `parental-controls`, `application-filter`, `ml-threat-detection`
