Netlify Redirects allow developers to control routing logic on the Edge from within their site's code and configuration, giving them more power over their site's routing. This can result in greater efficiencies and performance as the site is served from a location closer to the users. Jamstack sites can be immutable and atomic, making it easier to version and manage redirects along with the rest of the site's code. The new course on Jamstack Explorers provides free resources to help developers get the most out of Netlify Redirects, covering topics such as configuration, wildcards, placeholders, 404 rewrites and proxies, migrations, localization, and build optimizations. By using Netlify Redirects, developers can optimize their site's performance without needing specialized tools or expertise.
