well Just to let you know I heard at a CFUG meeting on the west Coast that
the next server to be shipped from allaire is going to be a combination of
the CF server and Jrun that they market Now. I veryfied this info. So well
This is going to consider the relative advantages and disadvantages of both.
I am betting on that product.

That is an advantage I see with CF it combines the three tires to give you a

Cf is reparsed each time. this is not ging to be the case in their new
version. Performance correction is minimise the quantity parsed each time.
