What is GoogleOther?
GoogleOther is a generic crawler used by various Google product teams for publicly accessible web crawling outside of Google Search. Introduced to provide transparency about Google's diverse crawling activities, this bot represents Google's R&D teams, product development, and other initiatives that need web data. The crawler might be used for research projects, new product development, or experimental features. By using GoogleOther, Google provides website owners with visibility into non-search related crawling while maintaining the ability to control access through robots.txt.

// Set cache headers
header('Cache-Control: public, max-age=3600');
header('X-Robots-Tag: noarchive');
// Optional: Serve cached version
if (file_exists('cache/' . md5($_SERVER['REQUEST_URI']) . '.html')) {
