Question

I’m using my own HTTP wrapper using sockets. So far everything works except multipart/form-data POST. When I send the data to server, it simply doesn’t respond, so I’m guessing I’m missing something in my POST like I would need “\r\n\r\n” for regular requests.

This is my request:

POST /getproxies/get.php HTTP/1.1
Host: myhost.com
User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:12.0) Gecko/20100101 Firefox/12.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-us,en;q=0.5
Cookie: sid=UtozR43zQQAtVA2Np0KP_ZLnO0IYwwU1S_Tt4Z3N80wctL; 
Connection: Close
Content-Type: multipart/form-data; boundary=---------------------------4664151417711
Content-Length: 411

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

---------------------------4664151417711
Content-Disposition: form-data; name="opt_2"

GET
---------------------------4664151417711--

When I send the data, the connection is open, like it would be waiting on the server, but server doesn’t respond. Any ideas what am I missing here? Thanks

Your boundary isn’t matching the one declared on the boundary= part.

Content-Type: multipart/form-data; boundary=AaB03x

--AaB03x
Content-Disposition: form-data; name="submit-name"

Larry
--AaB03x
Content-Disposition: form-data; name="files"; filename="file1.txt"
Content-Type: text/plain

... contents of file1.txt ...
--AaB03x--
