devops - Configure `:path` header for envoy ratelimiting

Question

I'm trying to use envoy ratelimiting functionality and need to ratelimit based on the entire url in my request, e.g. https://myenvoy.com/path/to/smth

Here is a part of my envoy.yaml

routes:
                - match: { prefix: "/" }
                  route: 
                    cluster: backend
                    rate_limits:
                      - stage: 0
                        actions:
                          - {request_headers: {header_name: ":path", descriptor_key: "path"}}

When I run

curl -k https://myenvoy.com/path/to/smth

The above configuration creates descriptor value /path/to/smth whereas I would like to have descriptor of value https://myenvoy.com/path/to/smth

Is it possible to configure that with envoy?

Thank you

PS: I looked at these header values and tried to use some, but it didn't help https://github.com/envoyproxy/envoy/blob/master/source/common/http/headers.h

Answer 1

From further investigation,

 - {request_headers: {header_name: "host", descriptor_key: "host"}}

does the job
