My suggestion would be to get all packets as they come and put them in
another buffer. Once the request is complete, send it to the httpd.
As to when it is complete, I am not sure if there are exceptions...

Hi,
Thanks you very much for that clarifications. It is really helpful to
understand where I should do something to fix my problem: the HTTP server.
Is there a way, by using another API than RAW API, to have TCP behaves
as I expect? If yes which API should I use?
Regards.
