Hello,

I am writing an application that makes a number of web service calls
to a variety of sources and aggregates the data back on a web page.  A
couple of the services require basic authentication information to be
sent as part of the post request in the http header.  I have tried
setting up a credential cache and passing it as part of the service
call, but when I do a tcp-trace of the resulting data, the credential
information isn't passed in either the soap header or the http header.
The rest of the message looks correct, but since the credentials
aren't making it to the service, the message is rejected.

Here is a copy of one of the routines:

  Private Sub btnGo_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles btnGo.Click
       Dim someService As aService.EmployeeService
       Dim credCache As System.Net.CredentialCache
       Dim netCredential As System.Net.NetworkCredential
       Dim myURI As System.Uri
       Dim EmployeeNumber as String
       Dim EmployeeName as String

       someService = New aCustomer.AccountService
       credCache = New System.Net.CredentialCache
       netCredential = New System.Net.NetworkCredential

       myURI = New System.Uri("http://hr1/services/EmployeeInfo")

       netCredential.UserName = "TestUser"
       netCredential.Password = Password.text
       EmployeeNumber = "12345"

       credCache.Add(myURI, "Basic", netCredential)

       someService.Credentials = credCache
       someService.PreAuthenticate = True

       EmployeeName =
someService.findByEmployeeNumber(EmployeeNumber)
   End Sub

Any help/guidance on how to add the credential information to the HTTP
header would be greatly appreciated.

Thanks
