[httperf] Application implementation

[Bhagwan Anjanappa]

Hi Martin,
    I have an application which implements an online Travel agency 
this has been tested on TPC-W bench mark. I am trying to test it on 
httperf. My question is Each client session should follow a pattern 
like: go to main page, sign in, browse flights, purchase tickets and 
check out. Now how can I find 

the probability that an item is added to the cart, given that it has 
been browsed.

the probability of proceeding to check out, given that it has been just 
added to the cart.

Is there a way to find all these probabilites and anything close to it.

ALSO ONE MAIN QUESTION IS CAN WE HAVE A VARIED REQUEST RATE WITHIN A 
SINGLE CLIENT SESSION as I know we can use the --period option to have 
an distributed session rate but the request rate within each client 
session is constant.

Thanking you for all the time and support.
Bhagwan
