I have added mapext=shapes to the URL, and the extents as defined in my 
mapfile include the entire data set in all shape files.  I've also tried 
using other SITEID numbers.  Here is a snippet from my map file defining 
some of the basics as well as including two shapefiles in the layer 
(skipping inclusion of the other 20+ layers):
