LWP Question

by Anonymous Monk
on Dec 10, 2012 at 18:34 UTC ( #1008147=perlquestion: print w/replies, xml ) Need Help??
Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I have a script that reads one of my pages to test it. the page it tests, will redirect to a number of different urls.

I use LWP to contact the page and get me the html of the page it loads. Some of them are identical source code.

I need to know what URL it is redirecting to.
How can I get that from LWP?

Here is my code:

my $ua = LWP::UserAgent->new; $ua->agent("Mozilla/8.0"); $ua->cookie_jar(HTTP::Cookies->new(file => "lwpcookies.txt", autosave => 1)); push @{$ua->requests_redirectable}, 'GET'; my $req = HTTP::Request->new(GET => "$_fileLoc"); $req->referer($_fileLoc); # Pass request to the user agent and get a response back $res = $ua->request($req); print $res->status_line, "\n"; if($res->status_line =~ /404 Not Found/i) { $_bad++; } else { if($res->is_success) { print $res->is_success, "\n"; if($res->status_line =~ /404 Not Found/i) { $_bad++; } else { $_cn = $res->content; print $_cn, "\n"; } } else { $_bad1++; $_errorT = $res->status_line; print qq~error: "~ . $_errorT . '"'. \t;#' } }
that is a section of my code.
How can I get this to only tell me the URL it redirected to? not the url it ended up on, but where it redirected to, like this: header("Location:"); have it give me the redirected url:, because someotherpath.php would also redirect to one other location, so I need the first one.

Can someone tell me how to do this?

Thank you.

    You might find this useful:
    #!/usr/bin/perl -l use strict; use warnings; use IO::Handle; use LWP::UserAgent; my $url = ''; my $ua = LWP::UserAgent->new( requests_redirectable => [], ); $ua->show_progress(1); my $res = $ua->get($url); print $res->request->uri->as_string; print $res->header('location');
