I'm trying to write a script to automatically upload reports in the form of XML files that I generate at work. The website uses form based file upload. Unfortunately, I've been having quite a few problems with it. Here is the code I'm using: 
    $request = POST ('http://www.environet.gov.on.ca/dwws-app/DWWSApp?
+cmd=UploadSubmPage.uploadSubm',
                     Content_Type => 'form-data', Content =>
                            [
                                works_id=>'300002167',
                                lab_id=>'48',
                                filename=>['260015626-220006440.txt']
                            ]
                    );

    print OutFile $request->as_string;
    
    $response = $ua->request($request, 'output2.html');

and the header it generates: 

POST http://www.environet.gov.on.ca/dwws-app/DWWSApp?cmd=UploadSubmPag
+e.uploadSubm
Content-Length: 3059
Content-Type: multipart/form-data; boundary=xYzZY

--xYzZY

Content-Disposition: form-data; name="works_id"



300002167

--xYzZY

Content-Disposition: form-data; name="lab_id"



48

--xYzZY

Content-Disposition: form-data; name="filename"; filename="260015626-2
+20006440.txt"

Content-Length: 2769

Content-Type: text/plain

This seems just dandy to me, however the server spits back an error that says 'Malformed line after disposition: Content-Length 2769'. It would appear that it doesn't like the next line. Why I'm not sure... Any suggestions on a course of action? Thanks, Tim.
