Hello Monks,

I am trying to POST to a Java servlet that is expecting multipart/form-data that conforms to W3C RFC-1341 section 7.2 . I am using LWP::UserAgent to generate the request, but it is not generating the boundary value in the HTTP headers. I have not seen any mention of a boundary value in any of the LWP related modules. According to the spec there should be a boundary=boundary_value after the Content-Type in the HTTP headers. Something like this;

Content-Type: multipart/form-data; boundary=_OPERAB__xxx

Do any of you wise people know how I can get the boundary in there. Do any of you have the Fonz like powers to tap my code and make the elusive boundary appear?

Here is the code: 
 my $ua  = LWP::UserAgent->new;
 my $req = HTTP::Request->new;

 $req->method('POST');
 $req->uri($servlet);
 $req->content_type('multipart/form-data');
 $req->content("xmlmsg=$xmlmsg");
 $req->authorization_basic($uid, $pass);

 # make the request to server
 my $res = $ua->request($req);
 print "\nREQUEST\n" . $req->as_string;
 print "\nRESPONSE\n" . $res->as_string;
