Hello

Just to be sure we're not misunderstood, the one without \r , that i agree with you should not be working is actually the only one working,  the correct one (see in second part) is the one not working 

//// first one working (with \r missing before content length)

echo -e  'POST /users/register-new_treat HTTP/1.1\r\nHost: en.tatolocal:8080\r\nAccept-Encoding: identity\nContent-Length: 13\r\nContent-Type: application/x-www-form-urlencoded\r\n\r\nusername=toto' | nc en.tatolocal 8080

it return me this 

HTTP/1.0 302 Found
Server: CppCMS-Embedded/1.0.3
Connection: close
Content-Type: text/html; charset=utf-8

which what i expect 

dump of the echo

Objet : Re: [Cppcms-users] 404 not found with valid URL and POST Request

Can you give a hexdump of your echo command, because with -e there is still a redundend new line (after content length) so the content that is sent is actually bigger than it should be.

It seems that because you do not put '\r' than the Content-Length is ignored and not treated.

Also can give the response of the web server.
