Thank you for the reply.

If my memory is not failling me, I have had the handler be called for
nonexistant files, and also for folder names - without changing the default
document.

But what you say seems to be working - at least insofar as the HttpModule
being triggered when the request is for any kind of .aspx.

However, I have moved the default.aspx-file to the top of the
default-documents list (which *is* enabled). the handler is still not
executed if I only request http://myserver/mywebsite

If I put in a file of that name, it works (as expected) - but this requires
a default.aspx in every subfolder, in order to get the httpmodule to process
BeginRequest.

This is *not* the behaviour I experienced this spring :/

So I am still wondering that something might have changed e.g. with the
introduction of WinXP sp2
