     Provides behavior for making common types of HTTP request methods and
     decides which type of request field encoding to use.
 
     Specifically,
 
     :meth:`.request_encode_url` is for sending requests whose fields are encoded
     in the URL (such as GET, HEAD, DELETE).
 
     :meth:`.request_encode_body` is for sending requests whose fields are
-    encoded in the *body* of the request using multipart or www-orm-urlencoded
+    encoded in the *body* of the request using multipart or www-form-urlencoded
     (such as for POST, PUT, PATCH).

     appropriate encoding format and use one of the above two methods to make
     the request.
