## Feature As the title, support `has` match, `local` that works the same with the `rewrites` and `redirects` of next.config.js on middleware config. With this PR, you can write the config like the following: ```js export const config = { matcher: [ "/foo", { source: "/bar" }, { source: "/baz", has: [ { type: 'header', key: 'x-my-header', value: 'my-value', } ] }, { source: "/en/asdf", locale: false, }, ] } ``` Also, fixes https://github.com/vercel/next.js/issues/39428 related https://github.com/vercel/edge-functions/issues/178, https://github.com/vercel/edge-functions/issues/179 - [x] Implements an existing feature request or RFC. Make sure the feature request has been accepted for implementation before opening a PR. - [ ] Related issues linked using `fixes #number` - [x] Integration tests added - [ ] Documentation added - [ ] Telemetry added. In case of a feature if it's used or not. - [ ] Errors have helpful link attached, see `contributing.md` Co-authored-by: JJ Kasper <jj@jjsweb.site>
