When I set Content-Type header to multipart/form-data and add data to
CURLOPT_POSTFIELDS it seems to hang. I thought maybe proxy issue but
tried with/without.
1) If sending simple string like a=foo&j=boo then there isn't an issue
2) If I don't set Content-Length then it doesn't hang, makes the post.
However receiving side doesn't get data (content length 172 but should
be 134610
Thanks for any help or pointers.
