how to redirect GCDWebServer requests to an external host from within an iOS app

Question

In my iOS app I'm trying to add a simple GCDWebServer redirect handler like so:

self.webServer!.addHandlerForMethod("GET", 
    pathRegex: "/api/.*",
    requestClass: GCDWebServerRequest.self,
    processBlock: { request in
        let url = NSURL(string: "http://external.host\(request.URL!.absoluteString)")
        return GCDWebServerResponse(redirect: url, permanent: true)
    }
)

but my url is malformed. How do I properly construct an NSURL from a given host and GCDWebServerRequest.URL ?

What is the value of `url`? It seems like your current construction might end up with two schemes, which would be invalid. — Aaron Brager, Oct 04 '15 at 23:40
Ah, it is `nil` ! It appears my `url` is indeed malformed. If I hardcode an external url such as `let url = NSURL(string: "http://external.host/api/playthrough_ids")` then it works. So I'll edit the question, to rephrase 'how to form a proper `NSURL` with host + `request.URL` — Robert Carter Mills, Oct 05 '15 at 00:10

request.URL is an NSURL object and as such, using it to form another url with a different host necessitates splitting it by accessing its path like so:

let url = NSURL(string: "http://host.com\(request.URL!.path)")
