Describe the feature you'd love to see

I'm looking to access a res.local. property inside my pathRewrite custom function, but it isn't passed in - just the path and the request object.

I've looked around and I don't immediately see anyone else asking about this, so perhaps it is a little unusual, but the res object is available where prepareProxyRequest is called and it could be passed down the chain like res is perhaps?

Additional context (optional)
