Submission + - HTTP Header Survey for the Top 10k Websites (shodanhq.com)
achillean writes: "A survey of Alexa's top 10,000 websites on the Internet was conducted to measure the usage of security-related HTTP headers, mobile awareness and potential information leakage. A few interesting results: Nikto is the most blocked user agent, followed by Wget and cURL. Sometimes websites forget to obfuscate all of their 'Server' header values (see qiyi.com), and many sites use different servers for different user agents (ex: live.com). The full dataset is available for download."
