In the end it will printout a web page including the necessary CGI headers.
B<rrdcgi> parses the contents of the template in 3 steps. In each step it looks

it starts neither with a '/' nor contains '..'. This is to make

The B<--lazy> option in RRD graph can be used to make sure that graphs
are only regenerated when they are out of date. The arguments

then you can access their output with this tag. The I<number> argument refers to the
