How these numbers are calculated

TechLeads scans public websites and detects RackCache from signals in the page HTML, scripts, cookies, HTTP headers and DNS records. Market share is RackCache's website count divided by the website counts of all Caching technologies we track; a site using two Caching tools counts for both. Counts were last refreshed on October 8, 2026 and update daily.
