Custom resolvers with callbacks

[jayaprabhakar]

At present custom resolvers are expected to return the target url immediately. As a dynamic proxy, there are some use cases like checking database. To make it easy it would be great to have the resolved target as callback instead of having to return immediately.

Thanks @manast.

I have the same use case but would also like to have access to the req to do authentication before proxying

Edit:
Thank you thank you thank you.
I no longer need this as I was able to use some of your code to make my http-proxy implementation do what I needed.
