Dim json As New Chilkat.JsonObject

// Create the following JSON:

//   "headers": [
//     "(request-target)",
//     "host",

// Indicate the names of the headers to be included in the signature.
// "(request-target)" is not actually a header name, but is a special name for HTTP signatures.
// Copy the following three lines of code exactly as-is.  
// Do not replace "host", "date", or "(request-target)" with values.
success = json.UpdateString("headers[0]","(request-target)")
success = json.UpdateString("headers[1]","host")

Dim http As New Chilkat.Http

// Setting the AuthSignature property causes the following header to be computed and added:
// Authorization: Signature keyId="...", algorithm="hmac-sha256", headers="(request-target) host date", signature="..."

http.SetRequestHeader "Cache-Control","no-cache"

// Chilkat will auto-add the Date header because it's needed by the HTTP Signature.
