I am trying to modify some old code (from 2006) to POST to an SNI enabled server. It is not working as I expect. According to everything I been able find the relevant modules are up-to-date enough to do this:

LWP             6.33
HTTP::Request   6.14
IO::Socket::SSL 2.056
OpenSSL         1.0.1

I still get an error 403. I can POST the data using wget so I am guessing there is a problem in how I setting it up. This outlines the procedure I am using.

use LWP;
use HTTP::Request;

sub post_cert 
  my ($url,$certificate,$encode,$certno) = @_;

  # create the user agent
  my $agent = new LWP::UserAgent or return (0,"Unable to create HTTP A
+gent");
  
  $agent->agent("Agent ID");
  
  # create a request
  my $request = new HTTP::Request POST=>$url;
  
  my $post = "Buncha XML Certificate Data";
  
  # set the host: header (for SNI)
  my ($host) = $url =~ m|https?://([^:/]+)|;
  $request->header("Host", $host);
   
  # ready -- load content
  $request->content($post);

  # fire
  $response = $agent->request($request);

  # aim
  if ($response->is_success) {
    undef $response;
    undef $request;
    undef $agent;
    $message = "$certno: send to $url successful";
    return (1,$message);
  }
  
  $message = "$certno: send to $url failed\n";
  $message .= "$certno: Remote said: " . $response->status_line . "\n"
+;
  undef $agent;

  return (0,$message);
}
