Would like to see ability to specify a small set of path prefixes to just deliver static content

Would be nice to be able to have the proxy deliver a small number of files directly.

The particular use case is to be able to easily enable support for LetsEncrypt directly against doorman without having to do it in the backend service - which may not be customizable.

i.e. something like

staticPaths: {
'/.well-known/acme-challenge/' : '/path/to/letsencrypt.sh/.acme-challenges/',
'/static/' : '/path/to/static/html/'
},
staticPathsPublic: {
'/robots.txt' : '/path/to/my/robots.txt'
},
