no they aren't. If you set a request variable in the application.cfm it's
pretty much the same as setting a local variable in terms of persistence...
every page will recreate the variable anew.
Request variables are different, though, from local variables in that they
can be seen inside of custom tags without specifically passing the
parameter.
One tecnique used often is to set the variable in the application scope in
the application.cfm page (using proper locking, of course) and then to copy
the variable into the request scope immediately after. This way you save
the cost of creating the variable every page load and/or locking a shared
scope every time the variable is used... and trade it for the smaller
footprint caused by copying the variable from the persistent shared scope to
the request scope.

|Brilliant! So what's the downside? The variables are not
