This is odd behaviour from RTKLIB (and invalid HTTP). The other NTRIP 
protocol agents I could find doing the same operation do not send 
anything after their GET request headers.

The RTKLIB sources show it sending a Connection::close. So to any HTTP 
agent(s) it will just be unwanted extra bytes on the TCP stream, they 
will be dropped and maybe logged.


To send any content in an HTTP/1.0 GET request requires the 
Content-Length header.

NTRIP protocol specification claims to be HTTP/1.1 compliant which means 
Transfer-Encoding is technically valid, although still semantically 
dubious for GET. Better just not to send content in GET.
