reverse proxy wcf endpoint hell

Hi everybody,

  for quite some days I am chewing on how to call a wcf service for a Silverlight app via apache reverse proxy correctly. The setting is as follows:

Apache reverse proxy called via https:

https://DmzServerURL/SL_App_01 is routed to

http://192.168.2.5/Sl_App_01/

Everything is working fine (Silverlight app shows up) up to the moment I need data from the SQL server. Depending on how I configure the endpoint I get either no errors and nothing is happening up to "No server found" etc.

I can call the svc by:

https://DmzServerURL/SL_App_01/WcfPortal.svc

and can see the correct svc URL using my internal server in the svcutil.exe call. I think I am missing some settings in web.config to use the internal svc adress.

After 3 days of reading the fog becomes thicker instead of getting a clue what to do.

Here are my Application_Startup and web.config:

The actual setting is in index.html - so I can change the endpoind without recompiling.

        private void Application_Startup(object sender, StartupEventArgs e)        {string cDataPortalUrlString   = "";string cBasicHttpSecurityMode = "none";if (e.InitParams.ContainsKey("prodUrl")) 
			{			cDataPortalUrlString = e.InitParams["prodUrl"];
			}if (e.InitParams.ContainsKey("BasicHttpSecurityMode")) 
			{				cBasicHttpSecurityMode = e.InitParams["BasicHttpSecurityMode"];							
			} 			Csla.ApplicationContext.DataPortalProxy		= typeof(Csla.DataPortalClient.WcfProxy).AssemblyQualifiedName;Csla.ApplicationContext.DataPortalUrlString = cDataPortalUrlString;			var binding = new BasicHttpBinding(); binding.MaxBufferSize = int.MaxValue; 

                        // some more binding properties

if (cBasicHttpSecurityMode.ToLower() == "none") 
			{binding.Security.Mode = BasicHttpSecurityMode.None ;
			}else
			{binding.Security.Mode = BasicHttpSecurityMode.Transport;
			}Csla.DataPortalClient.WcfProxy.DefaultBinding = binding;            this.RootVisual = new MainPage();        }

the crucial line in index.html is:

<param name="initParams" value="prodUrl=https://DmzServerURL/Sl_App_01/WcfPortal.svc, BasicHttpSecurityMode=None" />			

And this is my web.config:

<?xml version="1.0" encoding="utf-8"?><configuration><connectionStrings>	  <add 
		name="SqlConnStr" 
		connectionString="Data Source=localhost;Initial Catalog=DB_Name;Integrated Security= false;User ID=UserID;Password=*****"

Needless to say that the app works perfectly in an  local environment or without the reverse proxy on a web server.

Sorry for the long post - maybe somebody can help or at least push me in the right direction.

    regards

       TIA
