First and foremost: Performance. Why run the whole file, go through the whole variable/template registering and rendering process etc. just to show nothing in the end?

Next, you break UI consistency by not using the usual way of handling such errors: You need to code your error message yourself instead of using the standard no permissions message, which is phrased and thus works with multi language environments.

Last, but not least: There is a standard procedure in vB to do this, and that's the way I did it. Just look at the original files. And if there is a standard way, it should be used.

Anyway, I really don't follow your argumentation - how often do your Admins need to change which usergroups get access to a custom page? This does not seem like a weekly operation to me, does it? This is a set it and forget it decision, is it not?
