No response after authentication success in pentaho? - authentication

Question

I try to use Basic Authentication to make a login into Pentaho by using .NET code
My code is:
Dim request = WebRequest.Create("http://x.x.x.x:8080/pentaho/Home")
Dim authInfo As String = Convert.ToString(userName) & ":" & Convert.ToString(userPassword)
authInfo = Convert.ToBase64String(Encoding.[Default].GetBytes(authInfo))
request.Headers("Authorization") = "Basic " & authInfo
Dim response As WebResponse = request.GetResponse()
You can see that I pass the authorization header with Basic username:password with Base64 encode.
for the last line of above code
Dim response As WebResponse = request.GetResponse()
you can see that I get the response from pentaho server then assign to variable response
In running, I found that Pentaho can return response and put the value to variable response.It seem okay that the authentication is passed and I login successfully
but when I input a link http://x.x.x.x:8080/pentaho/Home the login page still prompt and I need to login again....
Do you know what code I missing so that the Pentaho cannot login auto after above code?
Thanks you much!!!!!

Answer 1

Have you tried putting it as parameters in the url i.e :
?userid=joe&password=password
However, looking at it again it seems if you're successfully getting a logged in response, then the next request you are not logged in then you have not preserved the session/cookie between those two requests. Easily done in java with httpclient, not so sure about .net
