I am playing with some rrd generated graphs, and I'd like to give the
period (day, week, month, year) as a parameter to the cgi. I'd also like to
give targets as parameter, but that is secondary.
But, I never trust input from the web to be what I want, or to be safe. So,
I want to check whether it's day/week/month/year and if it isn't, not even
try to start rrdgraph.
So, is there a way to check input values in rrdcgi? Or do I need to fall
back to a perl wrapper?
