I really hated that javascript answer above (bs answer imho).

This is more of an html question than a CGI one

While I have no clue what your frame structure looks like, here's some advice:

//index.pl
frame1 = foo1.pl
frame2 = foo2.pl
frame3 = foo3.pl

there's a form on frame1, and you want it to update frame1 frame2 and frame3 when it's submitted

the solution, specify target=_top

If you wish to update only 2 of the 3 available frames, the answer is the same, specify target=_top and update the entire frameset (if it's all in one frameset).

If you have 2 framesets, frameset1 which has frame1, and frameset2, which has frame2 and frame3, and you wish to update only frames 2 and 3, then just update frameset2, and frame1 can remain without changing.

I also sugguest you specify an expiration date for each of the pages, so people can take advantage of caching (this prolly means a the same get string)

If you have no idea what i'm talking about, form target

Now for the perl part

#!/usr/bin/perl -wT
#index.pl
use CGI qw/ :all /;
my $fs = param("fs") || 0; # frameset
my $fr = param("fr") || 0; # frame

## only numbers are acceptable

$fs =~ s/\D//g;
$fr =~ s/\D//g;

$fs ||= 0; # if they weren't defined, or were gibberish
$fr ||= 0; # they best be 0

$|=1; # unbuffer

print  header(-type => 'text/html', # cache only for five minutes
              -expires => '+5m'  ), # you clients that cache

if($fs == 1)
{
    &generate_frameset1();
}
elsif($fs ==2)
{
    if($fr == 2)
    {
        &generate_frame2();
    }
    elsif($fr == 3)
    {
        &generate_frame3()
    }
    else
    {
        &generate_frameset1();
    }
}
else
{
    &generate_frameset_all();
}
### ... the actual subroutines below
### index.pl writes something like
<frameset 1>
    <frame src ="index.pl?fs=1;fr=1;">

    <frameset 2>
        <frame src ="index.pl?fs=2;fr=3;">
        <frame src ="index.pl?fs=2;fr=3;">
    </frameset>
</frameset>

I think this is plenty to get you started, lemme if it helps out (and what you settle on).

Do remember, javascript is a client-side. paranoia, paranoia, paranoia...
