ASP.NET/VB: HttpWebRequest and Full Error Message from Remote Server

This code returns an error:
"The remote server returned an error: (405) Method Not Allowed."

This is because the remote server sent an error code header.

The remote server ALSO returned a friendly error message and I want to see what the remote server returned.  The error message contains information I need.  It is not good enough to know that the remote server returned an error header.  I want my code to tell me in full what the remote server returned.
<%@ Page Language="VB"%>
<%@Import namespace="System"%>
<%@Import namespace="System.Web"%>
<%@Import namespace="System.Net"%>
<%@Import namespace="System.IO"%>
<%@Import namespace="System.Text"%>

Dim data As String = "{""hello"": ""world"", ""number"": 555}"
Dim webRequest As HttpWebRequest = TryCast(WebRequest.Create("https://zuhqtr5.couchappy.com/"), HttpWebRequest)
Dim auth As String = "admin" & ":" & "password123"
auth = Convert.ToBase64String(Encoding.Default.GetBytes(auth))
webRequest.Headers("Authorization") = "Basic " & auth
webRequest.Method = "POST"
webRequest.ContentType = "application/json"
webRequest.ContentLength = data.Length
webRequest.Accept = "application/json"
webRequest.ReadWriteTimeout = 500000
Dim requestWriter As New StreamWriter(webRequest.GetRequestStream())
requestWriter.Write(data)
requestWriter.Close()
Dim webResp As HttpWebResponse = DirectCast(webRequest.GetResponse(), HttpWebResponse)
Dim webResult As Stream = webResp.GetResponseStream()
Dim result As New StreamReader(webResult)
HttpContext.Current.Response.Write(result.ReadToEnd())

The message is there... the method POST(strange) is not allowed. Can you check on the remote server? is POST method allowed?

You understand that it is a perfectly fine error message:  (405) Method Not Allowed right?

You will get this message in case the POST method is blocked on the server.
It might be blocked on remote server for many reasons, security being the foremost.
Do you have any control over the remote server?

Enclose this code in try ... catch block and see if you can extract the error information from exception that is thrown.
