Lasso to process all requests

[James Harvard <james.tech.lists@xxxxxxxxxxxxxxxxxxxxx>]

I want all requests to a virtual host to be processed by Lasso.  (The idea 
being that when someone goes to www.myhost.com/foobar  I can have lasso catch 
the 'foobar' part to do a search in a db.)

I started off by defining a .lasso file as the 404 error file for the v host & 
a custom Lasso error page, but that must be a 'non-optimal' way of doing it, 
because it must do something like:

1) WT looks for the file /foobar and can't find it
2) WT invokes '404.lasso' for error page
3) Lasso gets a request and looks for /foobar - can't find it
4) Lasso finally runs the custom Error.lasso file that I've defined

If I understand the WT docs correctly, I would need to define the Lasso 'Action 
Handler' as a pre-processor for the v host.  However, there doesn't appear to 
be an 'Action' defined for Lasso.  I can only imagine that WT knows to process 
.lasso files with Lasso from loading the plug-in - there certainly doesn't 
appear to be any Admin Server setting that controls this.

TIA,
