*> With the rrdcgi code 
*> 
*>   <SELECT NAME=RRD_NAME>
*> 
*> and the "MadisonSD-s0" item selected, how do I construct
*> the html tag
*> 
*>   <OPTION SELECTED> MadisonSD-s0
*> 
*> based on <RRD:CV RRD_NAME>??
*> 
*> With perl, I'd end up doing
*> 
*>   if ( $this_iface eq $form_data{'RRD_NAME'} ) {
*>     print "<OPTION SELECTED> $this_iface\n";
*>   } else {
*>     print "<OPTION> $this_iface\n";
*>   }

normally state is passed on using an INPUT filed of type hidden
