Using the HTTP server
*********************

Configuration
=============

The HTTP server comes with a couple of additional variables:

* :ref:`supybot.servers.http.favicon`: Path to the file which is shown to 
  browsers as favicon.
* :ref:`supybot.servers.http.hosts4`: The IPv4 addresses where the bot 
  will  bind. In most of the cases, you will use 0.0.0.0 (everything) or 
  127.0.0.1 (restricted to local connections). Defaults to 0.0.0.0
* :ref:`supybot.servers.http.hosts6`: The IPv6 addresses where the bot 
  will  bind. Defaults to empty.
* :ref:`supybot.servers.http.keepAlive`: Determines whether the HTTP server
  will run even if has nothing to serve. Defaults to False, because the 
  daemon might require changing the port, if it is already taken.
* :ref:`supybot.servers.http.port`: The port the bot will bind. May not 
  work if the number is below 1024. Defaults to 8080 (alternative HTTP port).


Using the server
================

At the root of the server, you will find a list of the plugins that
have a Web interface, and a link to them. Each plugin has one or more
subdirectories of its own.

You may also want to run Apache httpd or Nginx in front of Supybot's HTTP
server, if you want to use subdomains or load balancing.

Here is an example of Apache httpd configuration (I didn't test it
with the rewrite, please notify me whether it works or not):

.. code-block:: apache

    <VirtualHost 0.0.0.0:80>
        ServerName stats.yourdomain.org
        <Location />
                ProxyPass http://localhost:8080/webstats/
                SetEnv force-proxy-request-1.0 1
                SetEnv proxy-nokeepalive 1
                RewriteEngine On
                RewriteRule ^/webstats/(.*)$ /$1
        </Location>
    </VirtualHost>

Here is an example of the Nginx configuration.  Create a new site ``/etc/nginx/sites-enabled/bot``:

.. code-block:: nginx

    server {
        # Note that your default server should specify these ports
        listen 80;
        listen [::]:80;
        # If your default server also has HTTPS configured, uncomment
        # the following two listen lines to enable it for this vhost.
        #listen 443;
        #listen [::]:443;
        server_name stats.yourdomain.org;

    location / {
        proxy_pass http://localhost:8080/;
        }
    }

Note that any HTTP server which can provide a reverse proxy service
can be configured to act as an intermediary or front end for the
Limnoria HTTP server.  Configuring these alternatives is left as an
exercise to the system administrator (who ought to be familiar enough
with it already).


Templates
=========

Among the plugins which use the HTTP server, some use the standard templates
system which allows you to edit page templates in a standard way (for other
plugins, check their documentation).

Templates are located in the `data/web/` folder. There is a folder per plugin
(and a `generic` folder, which holds generic pages), and all file names end
with `.example`, which is the default template provided by the plugin.
To customize it, rename it to remove `.example` (for instance:
``mv fooplugin/foopage.html.example fooplugin/foopage.html``) and edit it
(either do it intuitively or check the plugin documentation to see how
it handles its templates).
