Subject RE: Extending JMeter with a new generative controller
Date Fri, 27 Sep 2002 17:01:34 GMT
I dont know what that means, but it really doesnt matter for my intended
purpose.  I have the logs from a server that is getting hit tens of
thousands of times a day from many many different browsers, and it is that
load which I want to simulate on another, staging server.  So, recordng my
browser actions wouldn't really help me any.  Unless I misunderstand what
this component does.


P.S.  I've seen your name on the lists and it appears you certainly are an
expert.  Can you point me to the source for the HTTP Request Generative
Controller?  Looking at it would help me a lot.

Have you used the proxy recording component to record your browser actions?
