运行环境：
这里以windows xp为例：

httpwatchpro-v7.2.23

ActivePython-v2.7.2.5

import win32com.client__author__ = 'sun'# Create a new instance of HttpWatch in IEcontrol = win32com.client.Dispatch('HttpWatch.Controller')plugin = control.IE.New()# Start Recording HTTP trafficplugin.Log.EnableFilter(False)plugin.Record()# Goto to the URL and wait for the page to be loadedplugin.GotoURL("http://www.baidu.com/")control.Wait(plugin, -1)# Stop recording HTTPplugin.Stop()if plugin.Log.Pages.Count != 0 :    print "\nPage Title: '", plugin.Log.Pages(0).Title , "'"    # Display summary statistics for page    summary = plugin.Log.Pages(0).Entries.Summary    print "Total time to load page (secs):      ", summary.Time    print "Number of bytes received on network: ", summary.BytesReceived    print "HTTP compression saving (bytes):     ", summary.CompressionSavedBytes    print "Number of round trips:               ", summary.RoundTrips    print "Number of errors:                    ", summary.Errors.Count# Close down IEplugin.CloseBrowser()

输出结果：
