     <p>Start an HTTP client profile:</p>
    
     <code><![CDATA[
-      8 > {ok, Pid} = inets:start(httpc, [{profile, foo}]).

     <p>The new profile has no proxy settings, so the connection is refused:</p>
       <code type="erl">
-      9 > httpc:request("http://www.erlang.org", foo). 
+      11 > httpc:request("http://www.erlang.org", foo).
       {error, econnrefused}</code>
 
     <p>Stop the HTTP client profile:</p>
     <code type="erl">

+      12 > inets:stop(httpc, foo).
       ok</code>
     
     <p>Alternative way to stop the HTTP client profile:</p>
     <code type="erl">
-      10 > inets:stop(httpc, Pid).
+      13 > inets:stop(httpc, Pid).
