Hi, Do following calls to Net::HTTP#post (or get...) use the same connection, i.e. do they use HTTP connection-alive? Some tests have shown me, that Net::HTTP is not thread-safe, i.e. I cannot call two #post methods concurrently. Is that true? I know, a simple solution is to create multiple HTTP objects, which works for me. Regards, Michael -- Michael Neumann merlin.zwo InfoDesign GmbH http://www.merlin-zwo.de
