Re: POST to multiple URLS


Found & taken from:
.NET 247 : ngfx-io - sending http post request

    'The function below takes an absolute URL and parameters in the form of
"param1=blah&m2=bloh", makes a POST request, and returns the resulting
HTML page as a string.

String
        Dim result As String = ""
        Dim myWriter As StreamWriter

        Dim objRequest As HttpWebRequest = WebRequest.Create(url)

        objRequest.ContentLength = params.Length
        objRequest.ContentType = "application/x-www-form-urlencoded"
        objRequest.KeepAlive = False

        Try
            myWriter = New StreamWriter(objRequest.GetRequestStream())
            myWriter.Write(params)
        Catch e As Exception
            Return e.Message
        Finally

        result = sr.ReadToEnd()
        sr.Close()

        myWriter.Close()

        Return result

    'The below code I created demostrates how to use the above function to 
send a POST request to an URL/page

        Dim str1 As String

        Try
            'First you have to identify the form field(s) together with 
their values that will be sent to the resulting URL/page

            'the readHtmlPage function will return a string which is the 
page from the POST request
            str1 = readHtmlPage("https://www.income.com.sg/i-

            'then you may continue to process the resulting page from the 
post request

URL.

e.g. Search Engine Submissions
list of urls to submit websites to.
