okay, so here it is.
in routes.py:
use_error_controller = True
in main.py (line 218):
# ##################################################
# access the requested application
# ##################################################
if not os.path.exists(request.folder):
if request.application=='init':
request.application = 'welcome'
redirect(html.URL(r=request))
use_error_controller = rewriteSymbols.get('use_error_controller',
None)
if use_error_controller == True:
request.application = 'error'
request.controller = 'default'
request.function = 'index'
request.folder = os.path.join(request.env.web2py_path,
'applications',
request.application) + '/'
else:
raise HTTP(400, error_message,
web2py_error='invalid application')
and then in error/default/index I can query the database for content
where url=request.path_info
