Now that we've seen how we can deal with request and response objects from the
8+
client side, we'll see how we can then use the same abstractions on the server

side. In this example we're going to create a simple HTTP Server in C++ using

Building the Server
61+
===================
62+
63+
Just like with the HTTP client, we can build this example by doing the following

on the shell::
65+
66+
$ cd ~/cpp-netlib

$ g++ -o hello_world_server \

The first two arguments to the ``server`` constructor are the host and

Sneak Peak
37+
==========
38+
39+
The :mod:`cpp-netlib` allows you to write semantically consistent code for
40+
making different kinds of higher level network applications.
41+
42+
The library allows for writing simple code like:
43+
44+
.. code-block:: c++
45+
46+
using namespace boost::network;
47+
using namespace boost::network::http;
48+
49+
client::request request_("http://www.boost.org/");
50+
request_ << header("Connection", "close");
51+
client client_;
52+
client::response response_ = client_.get(request);
53+
std::string body = body(response_);
54+
55+
For simple C++ HTTP client applications.
56+
57+
The :mod:`cpp-netlib` is being developed for eventual submission to Boost_.
