I wrote a perl script to send a request to HTTP server using LWP::UserAgent. The code is here:

-------------------------------------------------------- 
$url = 'http://151.104.234.14/voipadmin/security_chk';
$ua = new LWP::UserAgent;
$res = $ua->request(POST $url,
       Content => [ Submit => 'Submit',
                    user => 'admin',
                    passwd => 'password'
                  ]
        );

-------------------------------------------------------

When I use the microsoft network monitor to capture the packets, I found that the POST request is not sent correctly. It is sent twice. The 1st sending doesn't include the content (or data ) and the content is sent in the 2nd http request and is not sent as data. Here are the 2 frames I captured: 

--------- 1st frame POST request -----------
HTTP: POST Request (from client using port 34746)
HTTP: Request Method = POST
HTTP: Uniform ResourceIdentifier=/voipadmin/security_chk
HTTP: Protocol Version = HTTP/1.1
HTTP: Connection = Keep-Alive
HTTP: Host = 151.104.234.14
HTTP: User-Agent = libwww-perl/5.65
HTTP: Content-Length = 35
HTTP: Content-Type = application/x-www-form-urlencoded


--------- 2nd frame POST request -----------
HTTP: Submit=Submit&j_username=admin&j_password=password Request (from
+ client using p
HTTP: Request Method = Submit=Submit&user=admin&passwd=password
----------------------------------------------------

Obviously I don't get right response becasue the request is not sent correctly. The request should be sent in one packet, but look like LWP::UserAgent seperates message and send it twice. This is not correct. I check the Max_Size and it is undef (means there is no limit for the packet size). Anyone see this problem before? Any idea about this?

Thanks for your help.
