The Squeak HTTPSocket does this and I tested also with Pharo, only in HTTP mode no SSL/TLS.
 
(HTTPSocket httpPost: anUrl
     args: #() user: (self user) passwd: (self password)).
 
replace "self user" and "self password" wih the methods or instVars you have to retrieve your auth attributes

Asunto: [Pharo-project] Tip for using CurlPlugin against GData services ?

Has someone tried to use the CurlPlugin against an google data service? 
 
I'm searching for a feature/method to set the authentication field inside the HTTP-Header. 

I have no glue what method to use from the class Curl... 

Has someone a recipe/tip for me?

Thanks in advance
