easy:SetOpt_HTTPPost(formpost)
formpost argument.
Pass a HTTP post object as parameter. The easiest way to create such an object,
is to use hurl.Form() as documented.
Using POST with HTTP 1.1 implies the use of a "Expect: 100-continue" header.
You can disable this header with #CURLOPT_HTTPHEADER.
When setting #CURLOPT_HTTPPOST, it will automatically get
#CURLOPT_NOBODY to 0.
