Dummy Service

A simple, minimal express service for testing and debugging CDNs, load-balancers and proxies, as a safe, known backend. It will return all HTTP data sent to it.

There is a public instance running on dummy.now.sh.

With Dummy Service there are a couple of special-case headers which alter the behaviour of the service.

• Dummy-Status: This overrides the status-code returned by a given call. Defaults to 200. (e.g. return a 403)
• Dummy-Response: This overrides the response body returned by a given call. Otherwise will return all headers and cookies in a JSON blob. (e.g. return an error page)
• Dummy-Delay: This adds a delay (in microseconds) in the processing of the response, useful for testing a stalled origin. Defaults to off.
• Dummy-Cache-Control: This overrides the cache-control header returned. Defaults to private to prevent caching.
