A collection of tests for Signed Exchanges (SXG), a web technology that cryptographically signs content to be served by third parties while preserving original attribution and security context. Integrated into Google Search, it enables website prefetching while users browse search results, providing faster page loads and offline accessibility. Implementation requires an nginx module or Cloudflare ASX.
