This is OK unless a parameter is specified more than once as in '?ar=3&ar=2' - in this case Vars loses a value. The following is what I use: 
my %args = ();

# get cgi parameters into a hash.  preserve multi-valued
# parms
for my $p ( $cg->param() )
{
    my @tmp = $cg->param($p);
    if ( scalar @tmp == 1 )   { $args{$p} = $tmp[0] }
    else                      { $args{$p} = [ @tmp ] }
}

Now %args has your params, w/ multi-valued ones as references to arrays. - Bob Niederman
