+# Global Proxy
+It's possible to start the WireMockk server in Proxy mode, this means that all requests are proxied to the real URL. And the mappings can be recorded and saved.
+
+### Example
+Setup a proxy to samples.openweathermap.org
+
+``` c#
+var settings = new FluentMockServerSettings
+{
+    Urls = new[] { "https://localhost:9095/" },
+    StartAdminInterface = true,
+    ProxyAndRecordSettings = new ProxyAndRecordSettings
+    {
+        Url = "https://samples.openweathermap.org",
+        SaveMapping = true,
+        SaveMappingToFile = true,
+        SaveMappingForStatusCodePattern = "2xx"
+    }
+};
+
+var server = FluentMockServer.Start(settings);
+```
+
+You can now call (via an httpclient or just in browser) this URL: `https://localhost:9095/data/2.5/find?q=London&units=metric&appid=b6907d289e10d714a6e88b30761fae22`

 # Proxy stub mappings
 Proxy responses are defined in exactly the same manner as stubs, meaning that the same request matching criteria can be used.
