Functions

func RequestRawURL

func RequestRawURL(r *http.Request) string

RequestRawURL returns request original URL.

func RequestRemoteAddr

func RequestRemoteAddr(req *http.Request) string

RequestRemoteAddr finds the real remote address from request.

If the web server is behind an HTTP proxy or a load balancer, http.Request.RemoteAddr is IP of the proxy or load balancer. But most HTTP proxies and load balancers will attach a header to tell the web server request's real IP.

func RequestScheme

func RequestScheme(r *http.Request) string

RequestScheme try to parses request scheme.

If the web server is behind an HTTP proxy or a load balancer, it's hard to known if original request's scheme by http.Request.TLS property. Most HTTP proxies and load balancers will attach a header to tell upstream server the request's real scheme. So check if the header is set first.
