HTTP Proxy Authentication via SOAP

Hi,

I have created a deployable proxy to access webservices outside our corporate network.

Unfortunately this requires authentication via http proxy server.

I therefore made all the settings to the http service in the portal. But when accessing the SOAP service of the portal I still get "Proxy Authentication Required" as HTTP error.

As I understand is the SOAP service integrated in the WAS since EP 6.0 Stack 9. Do I have to make the proxy settings to the WAS as well? If yes, where?

Thanks Nicolas
