Without any malice intended, this is a somewhat hackish way to work
around the problem.

I have long had a plan to make cookies first-rate objects in VCL, using
a syntax something like:

	sub vcl_recv {
		if (req.cookie.CLIENT_STATE ~ "logged in") {
			do_something();
		}
	}

And the necessary changes are slowly bubbling up towards the top of my 
todo list, so hopefully it will make it into 3.0

Never attribute to malice what can adequately be explained by incompetence.
