Hi,
I just wanted to add the info that xins' suggestion was the one that helped me out in my VS2005 environment!
From the suggestion I've added:
req.ProtocolVersion = HttpVersion.Version10
req.ContentType = "application/x-www-form-urlencoded"
req.Proxy = System.Net.WebProxy.GetDefaultProxy()
req.AllowAutoRedirect = True
req.MaximumAutomaticRedirections = 10
req.UserAgent = "Mozilla/3.0 (compatible; My Browser/1.0)"
... and now everything is working fine.
Thanks a lot for this suggestion!

Hi, I have the exception:System.Net.WebException: The underlying connection was closed: Unable to connect to the remote server.
The code is:
Dim URL As String = sRemoteServer
Dim request As HttpWebRequest = WebRequest.Create(URL)
request.Method = "POST"
Dim writer As New System.IO.StreamWriter(request.GetRequestStream())
writer.Write(sParameters)
writer.Close()
Dim response As HttpWebResponse = request.GetResponse()
Dim reader As New System.IO.StreamReader(response.GetResponseStream( ))
Dim str As String = reader.ReadLine()
Could anyone help me, please?
Thanks in advance.

I'd like to specify I made a web application, not a web service.

Hi,
I'm using this in a class and it returns the response string:
Protected Const ORDERENVIRONMENT As String = "http://www.anyserver.com/order.aspx?ID="
Protected Function ProcessOrder(ByVal theID as Long, ByVal p1 as String, ByVal p2 as String) As String
Dim reqStrg As String = String.Empty
Dim req As System.Net.HttpWebRequest
Dim res As System.Net.HttpWebResponse
Dim sr As System.IO.StreamReader
Dim s As System.IO.Stream
Dim b As Byte()
Dim myResult As String = String.Empty
req = System.Net.WebRequest.Create(ORDERENVIRONMENT + theID.ToString())
reqStrg = "param1=" + Server.UrlEncode(p1) + "&"
reqStrg += "param2=" + Server.UrlEncode(p2)
b = System.Text.Encoding.ASCII.GetBytes(reqStrg)
req.Method = "post"
req.ContentType = "application/x-www-form-urlencoded"
req.KeepAlive = False
req.Timeout = 30000
req.ProtocolVersion = HttpVersion.Version10
req.ContentType = "application/x-www-form-urlencoded"
req.Proxy = System.Net.WebProxy.GetDefaultProxy()
req.AllowAutoRedirect = True
req.MaximumAutomaticRedirections = 10
req.UserAgent = "Mozilla/3.0 (compatible; My Browser/1.0)"
req.ContentLength = b.Length
s = req.GetRequestStream()
s.Write(b, 0, b.Length)
res = req.GetResponse()
sr = New System.IO.StreamReader(res.GetResponseStream())
myResult = sr.ReadToEnd
sr.Close()
res.Close()
Return myResult
End Function
Hope this is what you're looking for.

two things to check...
first is check if you are making ur web-service which is behind SSL.
it can be checked by opening inetmgr and go to properties for ur web site and check for directory security tab. here u wll find secure communications and an edit button. jst click on edit and make the setting "require ssl" to uncheckd and the try.
second : jst check your code in the web-service proxy which is being used by ur asp.net application. if "http" is thr then make it https if u want secure communcations
its jst an exp. m sharing here thr might be some other causes too.. :-)

Hi,
I still have this problem, when i tried many of the codes here the error changed to "remote server failed: 404 file not found"
I am trying to call a perl script from my .NET 1.1 code, this worked fine before firewall were turned on, but then I started getting these errors when the firewall was turned on on my IIS 6.0 server
Can anyone help?

request.Proxy = System.Net.WebProxy.GetDefaultProxy();
request.AllowAutoRedirect=true;
request.MaximumAutomaticRedirections=10;
request.Timeout=(int) new TimeSpan(0,0,60).TotalMilliseconds;
request.UserAgent="Mozilla/3.0 (compatible; My Browser/1.0)";
// end added codes
Stream writeStream = request.GetRequestStream();
byte[] bytes = System.Text.Encoding.ASCII.GetBytes(postsourcedata );
writeStream.Write(bytes, 0, bytes.Length);
writeStream.Close();
HttpWebResponse response = (HttpWebResponse) request.GetResponse();
Stream responseStream = response.GetResponseStream();
StreamReader readStream = new StreamReader (responseStream, Encoding.UTF8);
page = readStream.ReadToEnd();
}

I met this problem these days.And I found that
if Client's System Time is defferent from Server's System Time,a exception will be thrown.
"The underlying connection was closed: An unexpected error occurred on a receive."
Hope It works for you.
