[Grinder-use] How to use http persistent connection

[carol <hr...@16...>]

Dear,
       According to the grinder user guide, the default http connection is keep-alive. 
       But even I tried to request with a ‘‘Connection:Keep-Alive’’ header as show in the attached script, it seemed to be not a persistent connection。 
       Anything wrong with this script? How to request via a Http persistent connection by a worker thread?


      Waiting to hear from you,  


Yours sincerely,
