[go-nuts] Transparent Redirect Http Handler

Given a website with the following structure:

http://domain/ <-- ASP Website
http://domain/A <-- ASP Website
http://domain/B <-- Go Service
http://domain/B/A <-- Go Service

How would one make a visit to "/B/A" automatically return everything under
"/A"? Would this be a case for using the "NewSingleHostReverseProxy"
function in "net/http/httputil", or, would multiple HandleFuncs better
achieve the desired routing? If the latter, how would that even work,
given that "/A" is not part of the Go service? I'm guessing Go's proxy is
what's needed, but it's unclear how to use it in this scenario.

Sorry if this is elementary.
