If youre running a build command or site generator, the _redirects file should end up in the folder youre deploying. netlify redirect is not working with my create-react-app. Thankfully, Netlify provides an easy solution to handle redirects without having to fuss with unwieldy server configurations. It is also useful if you want to add custom headers for your proxy redirects, since this is not possible with a redirects file. So when someone requests /foo/bar.png, the redirect engine checks for the redirect rules and finds a match /*.

Redirects can also be used as a tool for gradually migrating to Netlify, or for adding a little Jamstack to your existing infrastructure. With internal rewrites, you can proxy from one Netlify site to another. So what is wrong with my code? A redirect is an explicit instruction by the server to find a specific resource elsewhere.

Generally, redirect rules are followed unless otherwise specified; If no conditional such as a role based or a GeoIP based redirect is present, Netlify's proxy server adheres to all redirect rules present. Its worth noting that should you include both a redirects file and redirect rules in your toml file, Netlify will prioritize the redirects file first before moving on to the .toml file. If you are proxying content to your site, custom headers will not be applied to that content.
