HTTP Conformance Testing

As part of our commitment to promoting a safer and more reliable internet, we conduct web crawls to identify and analyze websites that may be violating HTTP standards.

We recognize the importance of respecting website owners' privacy and autonomy and have implemented measures to minimize the potential negative impacts of our crawls. Our crawler is rate-limited to avoid overwhelming websites with excessive requests, and we only send syntactically valid requests that adhere to HTTP standards.

In addition, we provide website owners with the option to opt out of our crawls. To exclude your site from our analysis and future crawls, please send us an email at
