	// Description: 
	//       This FiddlerScript sample logs values from all currently 
	//       selected sessions to a file in Tab Separated Value (TSV) 
	//       format. 
	// Notes: 
	//       * The log file will be created in the Capture folder and 
	//         has the name: ResponseTiming.log 
	//       * Subsequent executions of this script will overwrite the 
	//         the previous ResponseTiming.log file. 
	//       * This script will run against any highlighted Fiddler 
	//         sessions, whether Capture is enabled or not, but it will 
	//         not automatically refresh the log if new Sessions are 
	//         captured. 
	// Version History: 
	//       * 2009-05-09: initial release 
	// Usage: 
	//        1. launch Fiddler 
	//        2. navigate to Rules > Customize Rules... 
	//        3. add the following text at the top of the file: 
	//                 import System.IO; 
	//        4. go to very end of file 
	//        5. paste all lines between 'start ResponseTiming' and 
	//          'end ResponseTiming' above the last close curly brace: } 
	//        6. choose Yes when prompted to Save Changes 
	//        7. navigate to Tools > Log ResponseTimes for Selected Sessions 
	//        8. open the .log file in %USERPROFILE%\Documents \Fiddler2\Capture
