+Configure an instance
+=====================
+
+While creating an instance, a configuration file is generated in::
+
+    $ (CW_INSTANCES_DIR) / <instance> / <configuration name>.conf
+
+For example::
+
+    /etc/cubicweb.d/myblog/all-in-one.conf
+
+It is a simple text file in the INI format
+(http://en.wikipedia.org/wiki/INI_file). In the following description,
+each option name is prefixed with its own section and followed by its
+default value if necessary, e.g. "`<section>.<option>` [value]."
+
+.. _`WebServerConfig`:
+
+Configuring the Web server
+--------------------------
+:`web.auth-model` [cookie]:
+    authentication mode, cookie or http
+:`web.realm`:
+    realm of the instance in http authentication mode
+:`web.http-session-time` [0]:
+    period of inactivity of an HTTP session before it closes automatically.
+    Duration in seconds, 0 meaning no expiration (or more exactly at the
+    closing of the browser client)
+
+:`main.anonymous-user`, `main.anonymous-password`:
+    login and password to use to connect to the RQL server with
+    HTTP anonymous connection. CWUser account should exist.
+
+:`main.base-url`:
+    url base site to be used to generate the urls of web pages
+
+Https configuration
+```````````````````
+It is possible to make a site accessible for anonymous http connections
+and https for authenticated users. This requires to
+use apache (for example) for redirection and the variable `main.https-url`
+of configuration file.
+
+For this to work you have to activate the following apache modules :
+
+* rewrite
+* proxy
+* http_proxy
+
+The command on Debian based systems for that is ::
+
+  a2enmod rewrite http_proxy proxy
+  /etc/init.d/apache2 restart
+
+:Example:
+
+   For an apache redirection of a site accessible via `http://localhost/demo`
+   and `https://localhost/demo` and actually running on port 8080, it
+   takes to the http:::
+
+     ProxyPreserveHost On
+     RewriteEngine On
+     RewriteCond %{REQUEST_URI} ^/demo
+     RewriteRule ^/demo$ /demo/
+     RewriteRule ^/demo/(.*) http://127.0.0.1:8080/$1 [L,P]
+
+   and for the https:::
+
+     ProxyPreserveHost On
+     RewriteEngine On
+     RewriteCond %{REQUEST_URI} ^/ demo
+     RewriteRule ^/demo$/demo/
+     RewriteRule ^/demo/(.*) http://127.0.0.1:8080/https/$1 [L,P]
+
+
+   and we will file in the all-in-one.conf of the instance:::
+
+     base-url = http://localhost/demo
+     https-url = https://localhost/demo
+
+Notice that if you simply want a site accessible through https, not *both* http
+and https, simply set `base-url` to the https url and the first section into your
+apache configuration (as you would have to do for an http configuration with an
+apache front-end).
+
+Setting up the web client
+-------------------------
+:`web.embed-allowed`:
+    regular expression matching sites which could be "embedded" in
+    the site (controllers 'embed')
+:`web.submit-url`:
+    url where the bugs encountered in the instance can be mailed to
+
+
+RQL server configuration
+------------------------
+:`main.host`:
+    host name if it can not be detected correctly
+:`main.pid-file`:
+    file where will be written the server pid
+:`main.uid`:
+    user account to use for launching the server when it is
+    root launched by init
+:`main.session-time [30*60]`:
+    timeout of a RQL session
+:`main.query-log-file`:
+    file where all requests RQL executed by the server are written
+
+
+Configuring e-mail
+------------------
+RQL and web server side:
+
+:`email.mangle-mails [no]`:
+    indicates whether the email addresses must be displayed as is or
+    transformed
+
+RQL server side:
+
+:`email.smtp-host [mail]`:
+    hostname hosting the SMTP server to use for outgoing mail
+:`email.smtp-port [25]`:
+    SMTP server port to use for outgoing mail
+:`email.sender-name`:
+    name to use for outgoing mail of the instance
+:`email.sender-addr`:
+    address for outgoing mail of the instance
+:`email.default dest-addrs`:
+    destination addresses by default, if used by the configuration of the
+    dissemination of the model (separated by commas)
+:`email.supervising-addrs`:
+    destination addresses of e-mails of supervision (separated by
+    commas)
+
+
+Configuring logging
+-------------------
+:`main.log-threshold`:
+    level of filtering messages (DEBUG, INFO, WARNING, ERROR)
+:`main.log-file`:
+    file to write messages
+
+
+.. _PersistentProperties:
+
+Configuring persistent properties
+---------------------------------
+Other configuration settings are in the form of entities `CWProperty`
+in the database. It must be edited via the web interface or by
+RQL queries.
+
+:`ui.encoding`:
+    Character encoding to use for the web
+:`navigation.short-line-size`:
+    number of characters for "short" display
+:`navigation.page-size`:
+    maximum number of entities to show per results page
+:`navigation.related-limit`:
+    number of related entities to show up on primary entity view
+:`navigation.combobox-limit`:
+    number of entities unrelated to show up on the drop-down lists of
+    the sight on an editing entity view
+
+Cross-Origin Resource Sharing
+-----------------------------
+
+CubicWeb provides some support for the CORS_ protocol. For now, the
+provided implementation only deals with access to a CubicWeb instance
+as a whole. Support for a finer granularity may be considered in the
+future.
+
+Specificities of the provided implementation:
+
+- ``Access-Control-Allow-Credentials`` is always true
+- ``Access-Control-Allow-Origin`` header in response will never be
+  ``*``
+- ``Access-Control-Expose-Headers`` can be configured globally (see below)
+- ``Access-Control-Max-Age`` can be configured globally (see below)
+- ``Access-Control-Allow-Methods`` can be configured globally (see below)
+- ``Access-Control-Allow-Headers`` can be configured globally (see below)
+
+
+A few parameters can be set to configure the CORS_ capabilities of CubicWeb.
+
+.. _CORS: http://www.w3.org/TR/cors/
+
+:`access-control-allow-origin`:
+   comma-separated list of allowed origin domains or "*" for any domain
+:`access-control-allow-methods`:
+   comma-separated list of allowed HTTP methods
+:`access-control-max-age`:
+   maximum age of cross-origin resource sharing (in seconds)
+:`access-control-allow-headers`:
+   comma-separated list of allowed HTTP custom headers (used in simple requests)
+:`access-control-expose-headers`:
+   comma-separated list of allowed HTTP custom headers (used in preflight requests)
+
