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

Dim http As New Chilkat.Http

' To save cookies to XML files (per domain) in a specific
' directory, set the CookieDir property (the directory must
' already exist and be writeable by the caller).  Also,
' set the SaveCookies property:
http.CookieDir = "/cookieDir"
http.SaveCookies = True

' Any methods that do a GET, POST, etc. will save cookies
' to the CookieDir:
Dim html As String
html = Await http.QuickGetStrAsync("https://www.paypal.com/")

' After running this code, a "paypal_com.xml" file should appear
' in /cookieDir.

' It's content will look something like this:


' <cookies>
'     <cookie key=".paypal.com,/" v="0" secure="yes">
'         <navcmd>_home-general</navcmd>
'         <HttpOnly />
'         <cwrClyrK4LoCV1fydGbAxiNL6iG>9cz...</cwrClyrK4LoCV1fydGbAxiNL6iG>
'     </cookie>
' </cookies>


' To cause cached cookies to be sent with 
' subsequent HTTP requests, set the SendCookies
' property = True.
http.SendCookies = True

' If another HTTP request is sent, the cookies should
' be added:
html = Await http.QuickGetStrAsync("https://www.paypal.com/")

' Check the LastHeader property to see the MIME header
' of the last HTTP request sent.
' The "Cookie" header field should be present.
Debug.WriteLine("--- LastHeader ---")
Debug.WriteLine(http.LastHeader)
