Before I dive into code, I need to explain our architecture. Three machines are involved: the clients are at a remote third-company site, the web-server is located in a DMZ, and we have a pubs server located inside our network that generates a PDF from xml that I send, after appliying business rules, etc.

Currently, I SFTP the file from the web server to the pubs server and redirect the client as such: 

my $redirectURL = 'http://'. $destination_server  . '/cgi-bin/pubtools
+/ebom.' . $extension . '?XML=' . $randomName;                 
                                                                      
+                 
##  copy our XML to the correct location/filename          
$logger->info("Report requested, FTP $localfile to $destination_server
+");                         

my $ftp = Net::SFTP->new($destination_server, Debug=>0);
$ftp->login($login, $pass) or $logger->error("Could not connect to Pub
+s Server");
$ftp->cwd($destination_path) or $logger->error("Could not change direc
+tories on Pubs Server");
$ftp->put($localfile, $randomName) or $logger->error("Could not transf
+er file to Pubs Server");
$ftp->site('chmod','0666',$randomName) or $logger->error("Could not ch
+mod remote file");
$ftp->quit;
                                                                      
+                                                              
## Now we redirect them to the generated PDF                          
+                 
$logger->info("Redirecting to $redirectURL");                         
+                 
print $cgi->redirect(-target => 'ResultWindow', -expires => 'now', -ur
+i=>$redirectURL);

Now, for security reasons, I can no longer let the client communicate directly to the pubs server, so everything has to go through the web server in the DMZ.

So instead of redirecting, I need to call this URL directly from the server and stream the data back to the browser. Any idea of how to do this? Thanks.
