Here is the script:
#!/usr/bin/perl -wT
use strict;
use HTTP::Request::Common;
use LWP::UserAgent;
use CGI;
use CGI::Carp qw(fatalsToBrowser);
my $q = new CGI;
my $ua = LWP::UserAgent-new;
if ($q-param(domain) =~ /\.ca$/) {
$ua-request(POST 'https://domains/perl/ca_reg.cgi', [
domain = $q-param(domain),
affiliate_id = $q-param(affiliate_id),
action = $q-param(lookup),
]);
} else {
$ua-request(POST 'https://domains/perl/reg_system.cgi', [
domain = $q-param(domain),
affiliate_id = $q-param(affiliate_id),
action = $q-param(lookup),
]);
}
Please do not hesitate to contact me directly if you have any more
questions!
assuming that the above is your script there is the
minor problem that it is not sending anything back to
the browser which is the 'exit prematurely' argument
what you will want to do is send a redirect back to
the browser to query the other scripts...
the other alternative is to use a piece of javascripting
that will resolve this on the client side before sending
a request back to the server.
you can think of this in terms of say
my @targets = qw(ca_reg.cgi ca_system.cgi);
my $index = 0;
my $jscript = 'script language=JavaScript type=text/javascript
!--
function doit(){
var base_uri = https://domains/perl/;;
var urls=new Array();' .\n;'
foreach my $targ (@targets)
{
$jscript .= 'urls[' . $index++ . ']=' . $targ . \;\n;
}
$jscript .= 'var nChosen = document.FormName.sysname.selectedIndex;
var wordup = base_uri + urls[nChosen];
document.FormName.action= wordup;
document.FormName.method = POST;
return true;
}
//--
/SCRIPT';
my $form = 'form name=FormName action=../ onsubmit=doit()
target=_top'
#
# the part where you stuff in the 'hidden values' you want,
# such as the domain,affiliate_id, etc... or put them in
# other things that this 'form' would send back
#
..
If you put that '$jscript' into the head.../head
and show your 'form' in the body.../body
when you user 'submits' it will go through the 'javascript'
to resolve the 'real method' and sent the Post to
the two scripts.

All of the information that I have found has said that you can not change the form action using IE, which is why I was led to the server side method. I will try the javascript, to see how it works! [..] If you really want to go with the server side push, then you will need to do something on the order of: # # stuff that resolves the uri into the form of a GET # print Content-Type: $type . $CRLF . Location: $uri . $CRLF . $CRLF; but I have not figured a way to get that to tell the browser to relocate to the $uri and retransmit the POST data along - have tried a few tricks, none of them worked out. the javascript idea was proposed here a while back, and I was hoping for what you are hoping for, but also it is not really an IE problem, unless it is a problem in pre-IE5 versions, but I do not have any versions of IE prior to 5.2 for Mac... But I can say that the trick I sent you is based upon code I have that works with IE5/IE6(win), Netscape 4, Netscape 6/7 Omniweb, Some times spinning up the javascripting IS the trick. ciao drieux --- -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
