Allows detailed interception and modification of HTTP requests and responses through handlers, enabling actions like adding headers or blocking sites based on conditions, as shown in examples for reddit.com blocking.

Designed as a standard net/http handler, making it easy to integrate with existing Go middleware and libraries, such as logging or compression, without extra setup.

Includes features like MITM certificate caching for performance optimization and supports multiple proxy modes, including HTTPS interception, suitable for real-world deployments.

Enables actions triggered by host equality or regex patterns, useful for targeted traffic control, such as time-based restrictions on specific domains.
