I AM doing an httpwebrequest POST to a url

What I need to do is multiple posts and do a single response stream if possible.

In my code below the response is kept "open" with the While "Canread" method.

The postdata goes in like this...but I can only send 7 at a time in the same POST
I NEED to send 7 at a time with a 3 second pause between posts"
<command><id>123</id></command>
<command><id>124</id></command>
<command><id>125</id></command>
<command><id>126</id></command>


And again...after the posts above run, I need to montor all the events

Dim sendWebRequest As HttpWebRequest = CType(WebRequest.Create(stUrl), HttpWebRequest)

sendWebRequest.SendChunked = True
sendWebRequest.Method = "POST"
sendWebRequest.ContentType = "text/plain"
sendWebRequest.KeepAlive = True
sendWebRequest.UserAgent = "CometTest"

'PUT A LOOP AROUNT THE getbytes???
Dim encodedData As New ASCIIEncoding()
Dim byteArray As Byte() = encodedData.GetBytes(postData)
sendWebRequest.ContentLength = byteArray.Length

Dim newStream As Stream = sendWebRequest.GetRequestStream()
newStream.Write(byteArray, 0, byteArray.Length)
newStream.Close()

Using myHttpWebResponse As HttpWebResponse = CType(sendWebRequest.GetResponse(), HttpWebResponse)

    Using streamResponse As Stream = myHttpWebResponse.GetResponseStream()

        'Next Line tricks into staying in Response Stream Loop
        While streamResponse.CanRead

Open in new window


              etc...
        End While

Modify following section

Dim newStream As Stream = sendWebRequest.GetRequestStream()
newStream.Write(byteArray, 0, byteArray.Length)
Thread.Sleep(4000)
newStream.Write(byteArray2, 0, byteArray2.Length)
Thread.Sleep(4000)
newStream.Write(byteArray3, 0, byteArray3.Length)
Thread.Sleep(4000)
...
newStream.Close()



You may want to utilize a loop.

CodeCruiser,
  How would that loop look?

What would it be around?

NOt sure where the byteArray2, 3 etc is coming form.

bytearray2, 3 etc are created by breaking your original xml to segments of 7 phones and then converting to byte array. Loop may look like

For i as integer = 0 to PhoneCount/7 - 1
      XmlString = GetXmlString(OriginalXML, StartIndex)
      ByteArray = GetByteArray(XmlString)
      newStream.Write(byteArray, 0, byteArray.Length)
      Thread.Sleep(4000)
Next


Note: Above is  just an algorithm not actual code.
