on_connect() is the function defined by server_iostream which is overloaded by

In it you can see how the server_http parses the incoming http request, gets a
response by calling on_request(), and sends it back using the helper routines
defined at the top of this file.
Therefore, if you want to modify the behavior of the HTTP server, for example,
to do some more complex data streaming requiring direct access to the
iostreams, then you can do so by defining your own on_connect() routine. In
particular, the default implementation shown below is a good starting point.
