 ## Composability 
 
 TODO: Use transformHeader to pre-configure URLs
 
-*)
+Currently, see tests/Config.fs (Header Transformer) to get an idea of how to tweak a builder for - e.g - a specific environment.
+
+An example with comments:
+*)
+
+open FsHttp
+open FsHttp.Operators
+
+let httpForMySpecialEnvironment =
+    let baseUrl = "http://my-special-environment"
+    http {
+        // we would like to have a fixed URL prefix for all requests.
+        // So we define a new builder that actually transforms the header.
+        // Since the description of method is a special thing,
+        // we have to change the URL for any method using a header transformer,
+        // like so:
+        config_transformHeader (fun (header: Header) ->
+            let address = baseUrl </> header.target.address.Value
+            { header with target.address = Some address })
+
+        // other header values can be just configured as usual:
+        AuthorizationBearer "**************"
+    }
+
+let response =
+    httpForMySpecialEnvironment {
+        GET "/api/v1/users"
+    }
+    |> Request.sendAsync
