FYI, you can do: myint = request.args(0, default=0, cast=int, otherwise='http://error_url')
The default value is returned if there is no arg at the index specified. If there is an arg, it attempts to use the function provided in cast to convert the arg. If that fails, it redirects to the URL specified in otherwise. I think all but the "default" argument is documented here: http://web2py.com/books/default/chapter/29/03?search=cast#An-image-blog, though would probably make sense to add documentation to the Core chapter where request.args is discussed, as the Overview chapter is a tutorial and not intended as a reference.
