Episode 65 of The Web Development Podcast with Fexingo digs into a subtle but impactful web performance and accessibility issue: ignoring HTTP content negotiation. Lucas and Luna explain how failing to serve the right Vary header or compress based on Accept-Encoding can make your app slower and less accessible, especially for users on slow networks or assistive tech. They walk through a real-world example involving a React-based e-commerce site that unnecessarily served 1080p images to mobile users and gzip to clients that support Brotli. The hosts also cover how proper content negotiation ties into server configuration, CDN caching, and even SEO. If your Lighthouse score seems fine but users still complain about load times, this episode might point to the culprit you've been overlooking.
