I have an client weather application that downloads forecast data from our 
server, on request, and need to cater for as many client network configurations 
as possible. The app can successful download using HTTP Proxy, both No 
Authentication and Basic Authentication however I am having problems with NTLM. 
To be frank, I'm not sure which THttpCli params/vars I need to set, on the 
client side, in order to allow the app to connect to the internet and therefore 
our server. In particular what format the username and password should be 

I have included a basic code snippet below. Any help greatly appreciated.

 if( CommOptionsPtr->UseHTTPProxy )
  if( CommOptionsPtr->HTTPProxyAuth == pxaNone ||
   CommOptionsPtr->HTTPProxyAuth == pxaBasic )
   HttpCli->Proxy   = CommOptionsPtr->HTTPProxy;
   HttpCli->ProxyPort  = CommOptionsPtr->HTTPProxyPort;

  if( CommOptionsPtr->HTTPProxyAuth == pxaBasic )
   HttpCli->ProxyUsername = CommOptionsPtr->HTTPProxyUser;
   HttpCli->ProxyPassword = CommOptionsPtr->HTTPProxyPass;

  if( CommOptionsPtr->HTTPProxyAuth == pxaNTLM ) //*************what params to 
set for this condition***************
   HttpCli->ProxyAuth = httpAuthNtlm;
   HttpCli->Proxy = "*" + CommOptionsPtr->HTTPProxyUser + "*" +
