I came across a paper which uses httperf to test a shopping cart
application here it says
"Each client session follows a simple pattern: go to main page, sign
in, browse products, add some products to shopping cart, check out,
repeat. Two parameters indirectly define the number of operations
within a session. One is the probability that an item is added to the
shopping cart given that it has just been browsed. The other is the
probability of proceeding to the checkout given that an item has just
been added to the cart. These probabilities vary sinusoidally between
0.42 and 0.7 with periods of 67 and 73 minutes, respectively"
How were the probabilites found? the numbers they give have been
collected after the testing.
