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]."

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.

: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:::

     RewriteCond %{REQUEST_URI} ^/demo

     RewriteRule ^/demo$ /demo/

     RewriteRule ^/demo/(.*) http://127.0.0.1:8080/$1 [L,P]

   and for the https:::

     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

Setting up the web client

-------------------------

:`web.embed-allowed`:

    regular expression matching sites which could be "embedded" in
