HttpWebRequest adding junk characters

Tech-Archive recommends: Speed Up your PC by fixing your registry

I am trying to invoke a remote Web Service that accepts XML data over https
but the server is returning a "The data at the root level is invalid. Line
1, position 1." error. I checked with the provider and he said that they
were receiving following on their server... Notice the weird junk characters
at the front...

<?xml version="1.0" encoding="utf-8"?>
<request><name>blah</blah><address>blah blah</address></request>

I checked the XML I am sending by writing it to a file instead of sending
over http and it was fine. I then created an ASP.NET web application that
took a request and wrote it out to a file. This also worked fine and there
were no junk characters in it. So I think the XML is being created correctly
and the only time there is a problem is when I am invoking a remote service
over https. Does anyone why the remote server is getting those junk
characters? Any suggestions are welcome...

I am using the following code to create my httpWebRequest

httpWebRequest = System.Net.WebRequest.Create(https://blah.blah.com)
httpWebRequest.Method = "POST"

httpWebRequest.ContentType = "text/xml"

Dim oProxy As WebProxy = WebProxy.GetDefaultProxy()

oProxy.Credentials = CredentialCache.DefaultCredentials

httpWebRequest.Proxy = oProxy

httpWebRequest.KeepAlive = False

httpWebRequest.ProtocolVersion = New System.Version("1.0")

httpWebRequest.Timeout = 12000


and following code to invoke the Web service

xmlWriter = New XmlTextWriter(httpRequest.GetRequestStream(),
System.Text.Encoding.UTF8)

With xmlWriter

..WriteStartDocument()

..WriteStartElement("request")

..WriteElementString("name", "blah")

..WriteElementString("address", "blah blah")

..WriteEndElement()

..WriteEndDocument()

..Flush()

..Close()

End With

xmlReader = New XmlTextReader(httpRequest.GetResponse().GetResponseStream())

Thanks in advance,

Sandeep
