Hi,
I am trying to send a message to the Business Partners. I was doing it successfully in the past. Now suddenly I started getting a message that the Underlying connection is closed. I did some research and found that the server has been put behind a Proxy Server. So I went and did the proxy settings in the HTTP send handler. Now I am getting the following message

"This request requires buffering of data for authentication or redirection to be successful."

Can someone please help?

Thanks,
Vivek
