HttpRequestFeature.Path does not match the request if contains encoded url

[UnoSD]

I am sending a simple request with the following URL:

http://localhost:5000/secrets/http%3A%2F%2Fwww.g

When I look at the Path property of the HttpRequestFeature, it contains:

/secrets/http:%252F%252Fwww.g

Instead of the expected value from the original URL. It looks like it has decoded the : and re-encoded the %.

I tried to track back to the setting of the property on the creation of the request from the context, but I get a bit lost in the feature collection, I am happy to help fixing this if someone could point me in the right direction.

The un-escaping of %3A is happening in the server (Kestrel/WebListener).

The double escaping of %2F to %252F is happening in PathString.ToUriComponent(). We should make this smart enough to recognize %XX and avoid double escaping.

@Tratcher Thanks, I'll have a glance at the Kestrel source.

Just for my understanding, why is it escaping at all? From the server perspective %2F is just a literal value part of the URL.
