perl HTTP request through IIS proxy server

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

HELP!!! I am writing a perl program to get some data out of an Oracle web site. I could not seem to pass our IIS proxy server. I am using ActivePerl "v5.6.1 built for MSWin32-x86-multi-thread".

Here are the codes:

use LWP::UserAgent;

my $ORASEARCH = 

'http://updates.oracle.com/ARULink/PatchSearch/process_form?product_fa
+mily=&product=&release=&platform=&language=0&patch_type

=&file=&orderby=abr.last_updated_date&process=Submit&email=&userid=&bu
+g=' ;

my $ORAUID    = 'userid' ;
my $ORAPASSWD = 'password' ;
my $LWPUA ;

{
    $LWPUA = LWP::UserAgent->new;

    print &lookup_patch_desc(1324710) ;
}


sub lookup_patch_desc
{
    my $BUGNO   = $_[0] ;
    my $REQUEST = HTTP::Request->new(GET => $ORASEARCH . $BUGNO);
    $REQUEST->header('Accept' => 'text/html') ;
    $LWPUA->proxy(http => 'http://proxy.mycompany.com:80/') ;
    $REQUEST->proxy_authorization_basic("windowuserid","windowpassword
+") ;
    $REQUEST->authorization_basic($ORAUID,$ORAPASSWD);

    return $LWPUA->request($REQUEST)->as_string;
}

Here are the outputs:

If your proxy server will accept challenge-response NTLM authentication only, then I doubt you can use LWP::UserAgent, as you need a client which can authenticate using your NT security context. The only suggestion I have is to look into the Win32::Internet client module. Since this uses microsoft's own wininet.dll file, if anything can pass on the proper NTLM authentication, it should be this system. More info here	[reply]

At work I am using Linux and I had problems getting out of the LAN till I found an NTLM Authorization Proxy Server by this guy. No need to boot windows to read PM, now. Just point Mozilla's proxy settings to localhost:5865. The little beast is written in python and also works on Windows. The stupider the astronaut, the easier it is to win the trip to Vega - A.

I don't know details of your Windows network environment, but have you tried passing the user id in the form of "`ntdomain\username`"? That's worked for me when I've been behind a Microsoft proxy. Very simple example at "(code) LWP with auth proxy". cheers, Don striving toward Perl Adept (it's pronounced "why-bick") Update: Ignore me and listen to brother meetraz. 8^p	[reply]
