When a site uses an ASP form using the "Post" method, I cannot connect to the site using an URL parsing the parameters with ? and &.

Does anybody know how to login to an ASP-site using this method for login-checking (for example from an PERL-script)?

Please note that many sites accept form post only from their own site by checking the page referal.

FreeBSD,

Took me some time to install ActivePerl on the Company Laptop, but finally ready for a testdrive...

Used your sample on a local .asp simulated ASP Page, which works fine:

Code:
# script.cgi ###############################
#!/usr/local/bin/perl

use LWP::UserAgent;
my $URL = "http://localhost/eunits/login.asp";
my $ua = new LWP::UserAgent;
$ua->timeout(30);
$ua->agent("AgentName/0.1 " . $ua->agent);
my $req = new HTTP::Request POST => $URL;
$req->content_type('application/x-www-form-urlencoded');
$req->content("BegPage=login.htm&PartID=123123123&EmpPIN=1234&Graphics.x=72&Graphics.y=5");
my $res = $ua->request($req);

if ($res->is_success) {
my $content = $res->content;
&output_status($content);
exit;
}
else {
&output_status("is_success Failed");
exit;
}

sub output_status {
my (@messages) = @_;
print "Content-type: text/htmlnn";
my $message;
foreach $message (@messages) {
print $message;
}
}
############################################

# login.asp ###############################
<%@ LANGUAGE="VBSCRIPT" %>

<HTML>
<HEAD>
<META NAME="GENERATOR" Content="Microsoft Visual InterDev 1.0">
<META HTTP-EQUIV="Content-Type" content="text/html; charset=iso-8859-1">
<TITLE>Login.htm</TITLE>
</HEAD>
<BODY TopMargin="0" Leftmargin="0">
<%For each i in request.form
response.write i & " = " & request.form(i) & " "
Next
%>

</BODY>
</HTML>

Result:
=======
C:WINDOWSDESKTOPperl>perl script
Content-type: text/html

<HTML>
<HEAD>
<META NAME="GENERATOR" Content="Microsoft Visual InterDev 1.0">
<META HTTP-EQUIV="Content-Type" content="text/html; charset=iso-8859-1">

<TITLE>Login.htm</TITLE>
</HEAD>
<BODY TopMargin="0" Leftmargin="0">
BegPage = login.htm PartID = 123123123 EmpPIN = 1234 Graphics.x
= 72 Graphics.y = 5 

</BODY>
</HTML>

So the local listener page is able to interpret the posted object.

When I run the script to the actual page which is located at "https://eunits.ac.com/login.asp" (with correct data), I get result:

C:WINDOWSDESKTOPperl>perl script
Content-type: text/html

is_success Failed

Any suggestions on how to get the actual result from the login.asp page returned?

Secure pages work differently. Have a look at -> http://www.devshed.com/Talk/Forums/Forum5/HTML/001630.html
