Hi once again. I'm about to start going back (grrrr) and locking all
my session, application variables, etc properly. Got a couple
question.
1. Suppose I'm creations a session variable FROM session variables.
For instance:
I have: session.subtotal, session.tax, and session.shipping. I want
to create a total:
<cfset session.total = session.subtotal + session.tax + session.shipping>
What kind of lock would go around that? Or would it be best to set a
local variable inside a Readonly lock then set the session.total
inside an exclusive lock from the local variable.
<cflock timeout="30" type="readonly" scope="session">
<cfset total = session.subtotal + session.tax + session.shipping>
</cflock>
<cflock timeout="30" type="exclusive" scope="session">
<cfset session.total = total>
</cflock>
2. I've got a million instances of passing cfid and cftoken as
session.id if cookies are turned off as per Ben Forta's examples in
his book.
a href = "somepage.cfm?#session.id#"
That means I need to put a readonly lock around all of those,
correct? My question is (actually a two part question).
If I have a block of these, such as a text menu, should I put one
lock around the entire block? Or should I lock each link separately?
Part B of this question: Since I'm going through the hassle of
checking for the existence of cookies, AND passing the session.id,
would it be better to just pass
cfid=#client.cfid#&cftoken=#client.cftoken# and not worry about if
cookies are turned on? I suppose even if I do that, I should put a
readonly lock around the links anyway, huh?
Geesh. Sorry for being so long-winded. :)
