LWP::UserAgent Get a page after authenicating SSL

Posted by powersakthi (powersakthi), 29 August 2007
LWP::UserAgent Get a page after authenicating in SSL mode Hi All,
I am using LWP::UserAgent and HTML::TreeBuilder to communicate to the below site
Here is the website map: which asks for two fields
then submit button
the form is submitted to
which validates the login credentials and if validated then user is redirected to main.asp and there will be a link called
which will have field
and after typing the serialnumber and hitting submit button the data is POST'ed to data.asp and details like
1) Manufacured_date
2) Model
3) Site .e.t.c comes in a tabular format.

Now the requirement:
I have to write a perl script which will do all these jobs behind the screen using LWP::UserAgent and use HTML::TreeBuilder. Since the site is SSL based i used CRYPT:SSLeay. Now my program looks like this

use strict;
use warnings;
use LWP::UserAgent;
use HTML::TreeBuilder;

my $ua = LWP::UserAgent->new( agent => 'Mozilla/5.0' );

my $response1 = $ua->post(
' ', [
"user_id" => "anonymous","user_pwd" => "password",

my $response = $ua->post(
'', [
"tx_Sno" => "T450W34990",]
print $response->status_line;
print $response1->status_line;
print $response->content;
print $response1->content;

The output is Status ok but the login data.asp is not getting into the session and it returns the response..
which means the session created by response1 is not applying to response POST. Can anyone help me how to handle this situation

hmmm...... never mind

Slightly educated wild guess.   You mention an ASP session.   Is there a cookie associated with that which you need to pass on to the second and subsequent POSTs?

FYI: this person has been advised about the possibility of needing to send/recieve cookies on two out of four forums he posted this question on. Your suggestion now makes that three. So far he has not replied to any posts on any of the  forums.

Thanks, Kevin ... I tend to look on the bright side and say "oh good - I probably made the right guess"   ... and remember that in some cultures saying "Thank you" does not come naturally.

To be honest, there are times that I enjoy a quick challenge such as this one, so I'll answer even if there might be elements of "spray" posting.  Been around long enough not to expect a response every time.

Yea, I can see you are a generous person when it comes to assisting the people that post questions here (for good reason). I have a good 10 years on forums under my belt so I have seen it all pretty much.
