AFAIK, the only interceptor that does this is for serving resources.

Which one does it? (ring-middlewares/resource document-root)?

@U368JQA01 it’s based on the bits of ring’s resource middleware. When :io.pedestal.http/resource-path is present in the service map, the value is used as the resource path root.

i.e. the resources are mounted into the route at :io.pedestal.http/resource-path? And hence the middleware treats every path it sees in the route as relative to that resource-path?

i.e. with a route containing "/my/resources/" -> resource-middleware and resource-path=/my, the resource-middleware would look for "/resources/" in the resource directory / classpath?
