Use case:
- I’m proxying an app (Hugo)
- If a URL does not exist there, I want to serve it from an older version of the site
I’ve modified http-proxy-middleware to enable it to fall-through to the middleware chain (see WIP PR, which depends on this one) when it encounters a 404 but without this PR, node-http-proxy already writes out the headers and so we cannot serve the fallback content.
Further context: https://github.com/chimurai/http-proxy-middleware/issues/248#
Summary of merge request
- Add
fallthrough
option to the context. If present, 404 responses from the target will not be handled by node-http-proxy so that they can fall through to the middleware chain by the consumer.
