Re: Connections through a HTTP proxy

[Hannes Wallnoefer <ha...@helma.at>]

Yes, I think we should add a method with your code for setting the HTTP 
proxy to XmlRpcClient.

System.setProperty() is a static method and it sets the property for the 
whole runtime, so it won't be possible to set the proxy per client 
instance. I would propose to add a static method

  public static void setHttpProxy (String host, int port, String auth)

to XmlRpcClient.
