How To Setup Apache Server
--------------------------
- mod_netconf compilation requires apache2-devel and libjson-devel packages.

- run following commands in this directory
$ make
# make install

- Add following lines into the (appropriate parts of the ) Apache configuration:
LoadModule netconf_module                 /usr/lib64/apache2/mod_netconf.so

- Start Apache

- For testing, you can run test-client
  - run under the same user as Apache, or change access rights of the
    communication socket (/tmp/pconn.sock) to allow writing.

    
mod_netconf Message Format
--------------------------

UNIX socket (with default path /tmp/mod_netconf.sock) is used for communication
with mod_netconf daemon. Messages are formated using JSON and encoded using
Chunked Framing Mechanism described in RFC6242 (http://tools.ietf.org/html/rfc6242#section-4.2)
with the following content.
Client is free to send multiple requests when the communication socket
to the mod_netconf daemon is opened.
