Dim http As New Chilkat.Http

' Returns the contents of the response body.
Dim jsonText As String = http.QuickGetStr("https://chilkatsoft.com/helloWorld.json")

' Examine the response status code.
Debug.WriteLine("response status code: " & http.LastStatus)

' Examine the response status text
Debug.WriteLine("response status text: " & http.LastStatusText)

' Examine the full response header.
Debug.WriteLine("response header:")
Debug.WriteLine(http.LastResponseHeader)
Debug.WriteLine("----")

' Examine the response content-type
Debug.WriteLine("LastContentType = " & http.LastContentType)

' Examine the response last-mod date
Debug.WriteLine("LastModDate = " & http.LastModDate)

' Load the response header into a Chilkat MIME object to access its fields individually.
Dim mime As New Chilkat.Mime
mime.LoadMime(http.LastResponseHeader)

Dim numHeaders As Integer = mime.NumHeaderFields
Dim i As Integer = 0
Debug.WriteLine("---- MIME Headers ----")
While i < numHeaders
    Debug.WriteLine("name:  " & mime.GetHeaderFieldName(i))
    Debug.WriteLine("value: " & mime.GetHeaderFieldValue(i))
    i = i + 1
End While
Debug.WriteLine("----")

' Get a header field value by name:
Debug.WriteLine("ETag: " & mime.GetHeaderField("ETag"))
