411 responses are delivered twice

[kenballus]

When Mongoose receives an HTTP/1.1 POST request with no Content-Length or Transfer-Encoding header, it responds with two 411 responses instead of 1.

To see this for yourself,

• Clone and build the current master branch (bdfa0b3)
• Start the http-server example under tutorials/http/http-server
• Send it a POST request with no headers:

POST / HTTP/1.1\r\n
\r\n

• Observe that you receive two responses:

HTTP/1.1 411 Length Required
Content-Length: 0

HTTP/1.1 411 Length Required
Content-Length: 0

Thank you.
They are not delivered twice, they are delivered again and again as long as the connection is kept open, every time the event manager runs. It is a consequence of #2806.
We'll work on it.
