 ## 0.6.0.1
 
 * Introduce a "semi cached body" to let the beginning of a request body be retried [#34](https://github.com/fpco/http-reverse-proxy/issues/34)
+* Add `wpsLogRequest` function which provides the ability to log the

+## HTTPS example to proxy bing.com
+
+The following example sets up reverse proxying froming to www.bing.com
+from localhost port 3000:
+
+``` haskell
+import Network.HTTP.Client.TLS
+import Network.HTTP.ReverseProxy
+import Network.Wai
+import Network.Wai.Handler.Warp (run)
+
+main :: IO ()
+main = bingExample >>= run 3000
+
+bingExample :: IO Application
+bingExample = do
+  manager <- newTlsManager
+  pure $
+    waiProxyToSettings
+      ( \request ->
+          return $
+            WPRModifiedRequestSecure
+              ( request
+                  { requestHeaders = [("Host", "www.bing.com")]

+              )
+              (ProxyDest "www.bing.com" 443)
+      )
+      defaultWaiProxySettings {wpsLogRequest = print}

 synopsis:            Reverse proxy HTTP requests, either over raw sockets or with WAI
 description:         Provides a simple means of reverse-proxying HTTP requests. The raw approach uses the same technique as leveraged by keter, whereas the WAI approach performs full request/response parsing via WAI and http-conduit.
