import 'package:chilkat/chilkat.dart';

void main() {
  // This example assumes the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  final http = CkHttp();

  // Set the SessionLogFilename property so that the Chilkat HTTP component
  // logs the exact HTTP requests and responses to a file.

  // The SessionLogFilename may be used with any of the HTTP
  // methods for sending GET, POST, PUT, DELETE, HEAD, etc.
  http.sessionLogFilename = 'c:/temp/httpSessionLog.txt';

  // Try a simple HTTP GET and then examine the session log:
  final String html;
  try {
    html = http.quickGetStr('http://www.chilkatsoft.com/httpTest/abc.html');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // The contents of the session log file after doing 
  // the GET request:

  // 	---- Sending ----
