Yes, that was the reason for the quotes. I am referring to the
mechanism by which lift determines that a page required ajax, so it
makes sure to include liftAjax.js.

Yes. As I indicate below (albeit in a messy fashion) the callbacks
which use liftAjax are defined before liftAjax.js is included.
Further, the variables which are needed by liftAjax.js, such as
lift_page, are defined *after* liftAjax.js is
included.
This is what lead me to believe that these three sections are being
rendered in reverse.
What I would expect to see is lift_page being rendered before the
inclusion of liftAjax.js which occurs before
the definition of the functions which rely on liftAjax.

That is fine, should one expect a SessionVar to work for a CometActor
when it is set in response to a RewriteRequest?
