Message exchange issues in example

[nilshenrich]

Running the continuous mode of the example doesn't behave as expected.

• TCP
  • Fragmented
  • Client -> Server: Works as expected, message displayed on terminal
  • Server -> Client: Works as expected, message displayed on terminal
  • Continuous
  • Client -> Server: Works as expected, new file is created and content written immediately
  • Server -> Client: File created on runtime start, but no content written to. Only if client runtime is closed, content is written twice
• TLS
  • Fragmented
  • Client -> Server: No message seems received
  • Server -> Client: No response, but expected if server doesn't receive a message
  • Continuous
  • Client -> Server: No message seems received, no new file created
  • Server -> Client: No response, but expected if server doesn't receive a message

This behaviour is tested in unit tests using stringstream. No bugs found here, example works with file stream.

Add ::std::flush to ostream to immediately update the stream. Won't fix all issues, but makes the file being updated while runtime is running

[nilshenrich]

The continuous TCP message from server to client is not sent twice, but the same message is sent on connection init and message received

Not TLS messages sent because I forgot to create certificates before.\ With 5dad8e6330ad3e9392f9842bf4871b78242d7fd1 the certificates are created automatically when compiling the example
