' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim http As New Chilkat.Http

' The Cookie header field has this format:
' Cookie: name1=value1 [; name2=value2] ...

' Build an HTTP POST request:
Dim req As New Chilkat.HttpRequest
req.SetFromUrl("http://www.chilkatsoft.com/echoPost.asp")
req.HttpVerb = "POST"

req.AddParam("param1","value1")
req.AddParam("param2","value2")

' To add cookies to any HTTP request sent by a Chilkat HTTP method
' that uses an HTTP request object, add the cookies to the
' request object by calling AddHeader.  

' Add two cookies:
req.AddHeader("Cookie","user=""mary""; city=""Chicago""")

' Send the HTTP POST.  
' (The cookies are sent as part of the HTTP header.)

Dim resp As Chilkat.HttpResponse
Dim domain As String = "www.chilkatsoft.com"
Dim port As Integer = 80
Dim ssl As Boolean = False
resp = http.SynchronousRequest(domain,port,ssl,req)
If (http.LastMethodSuccess <> True) Then
    Debug.WriteLine(http.LastErrorText)
    Exit Sub
End If


' Display the HTML body of the response.
If (resp.StatusCode = 200) Then
    ' Show the last HTTP request header sent, which should include
    ' our cookies...
    Debug.WriteLine(http.LastHeader)
Else
    Debug.WriteLine("HTTP Response Status = " & resp.StatusCode)
End If




Debug.WriteLine("---------------------")

' Some Chilkat HTTP methods do not use an HTTP request object. 
' For these methods, such as for QuickGetStr, cookies (or any HTTP request header) 
' are added by calling SetRequestHeader.  
http.SetRequestHeader("Cookie","user=""mary""; city=""Chicago""")

Dim html As String = http.QuickGetStr("http://www.w3.org/")
If (http.LastMethodSuccess <> True) Then
    Debug.WriteLine(http.LastErrorText)
Else
    ' Show the last HTTP request header sent, which should include
    ' our cookies...
    Debug.WriteLine(http.LastHeader)
End If
