Sorry, spoke too soon. I saw how auth works and did something similar.
right now it is something like this, mind that names can be changed:
@req_args.requires_validVars( 'www.google.com',
('search',),
('search','highlight'))
first param is where to redirect on error and the other params are
tuples of possible vars. In this case it validates if you pass
?search=... OR
search=... AND highlight=... and redirects on all other cases (missing
params or too many params)
Any suggestions? I could see this also validating the type of each
parameter (like string or number)...
I'll clean up the code later and release it then.
Regards,
Tiago
