I need to know if a server supports HTTP 1.0. I send this message through a TCP socket:
GET / HTTP/1.0
I need to know if a server supports HTTP 1.0.
When you send the request
GET / HTTP/1.0 you're telling the server that the HTTP version you as a client support is 1.0.
If a server is either designed for HTTP 1.0 or designed for HTTP 1.1 with backwards compability to 1.0 then the server should send a 1.0 response to a 1.0 request, not a 1.1 response since the response might not be supported by the client.
