Disable setting "Expect 100" in request header when request data size…

… is larger than 1024 bytes (#264) Curl automatically sets it when the request is a POST and the data size is larger than 1024 bytes. Requests with the Expect: 100-Continue header have an increased probability of becoming separated from one another, and hence returning with an error. It can be disabled via setting the Expect: header to the empty string. Signed-off-by: Shrikant Temburwar <[email protected]>
