I’m making a class to POST something on a web page that needs the headers and
data to be in the same package. I have tried the following but nothing
helps(I always get a packet with headers and one with data).

System.Net.ServicePointManager.Expect100Continue = false;
Request.AllowWriteStreamBuffering = false;
Request.ContentType = "application/x-www-form-urlencoded";

According to the documentation about
system.Net.ServicePointManager.Expect100Continue setting this to false
ensures that data and headers are send together, but it does not work this
way.

Does anyone know a solution for this problem?

There is no notion of packets in HTTP, just requests and responses. All
ServicePointManager.Expect100Continue does is add or suppress HTTP 1.1
Expect headers, so you either have one or two request/response pairs. How
many actual network packets are being sent depends on the underlying network
stack.

Martin,

Try moving your Expect100Continue = false call up to before you open your
socket. Not sure how soon this flag has to be set, but putting it before
the Create() works for me. :)
