 |svn| With Write Over HTTP
 --------------------------
 
-To use |svn| with write access, the currently supported method is over HTTP.
-This requires you to configure your local machine so that it can access your
-|RCE| instance.
+To use |svn| with read/write support over the |svn| protocol, you have to
+configure HTTP |svn| backend.
 
 Prerequisites
 ^^^^^^^^^^^^^
 
-- Enable lab setting on your |RCE| instance, see :ref:`lab-settings`.
-- You need to install the following tools on your local machine: ``Apache`` and
-  ``mod_dav_svn``. Use the following Ubuntu as an example.
+- Enable HTTP support inside labs setting on your |RCE| instance,
+  see :ref:`lab-settings`.
+- You need to install the following tools on the machine that is running an
+  instance of |RCE|:
+  ``Apache HTTP Server`` and
+  ``mod_dav_svn``.
+
+
+Using Ubuntu Distribution as an example you can run:
 
 .. code-block:: bash

    It is recommended to run Apache on a port other than 80, due to possible
    conflicts with other HTTP servers like nginx. To do this, set the
    ``Listen`` parameter in the ``/etc/apache2/ports.conf`` file, for example
-   ``Listen 8090``
+   ``Listen 8090``.
+
+
+.. warning::
 
-   It is also recommended to run apache as the same user as |RCE|, otherwise
-   permission issues could occur. To do this edit the ``/etc/apache2/envvars``
+   Make sure your Apache instance which runs the mod_dav_svn module is
+   only accessible by RhodeCode. Otherwise everyone is able to browse
+   the repositories or run subversion operations (checkout/commit/etc.).

+It is also recommended to run apache as the same user as |RCE|, otherwise

    .. code-block:: apache
 
-      export APACHE_RUN_USER=ubuntu
-      export APACHE_RUN_GROUP=ubuntu
+      export APACHE_RUN_USER=rhodecode
+      export APACHE_RUN_GROUP=rhodecode
 
 1. To configure Apache, create and edit a virtual hosts file, for example
-   :file:`/etc/apache2/sites-available/default.conf`, or create another
-   virtual hosts file and add a location section inside the
-   ``<VirtualHost>`` section.
+   :file:`/etc/apache2/sites-available/default.conf`. Below is an example
+   how to use one with auto-generated config ```mod_dav_svn.conf```
+   from configured |RCE| instance.
 
 .. code-block:: apache
 
-    <Location />
-        DAV svn
-        # Must be explicit path, relative not supported
-        SVNParentPath /PATH/TO/REPOSITORIES
-        SVNListParentPath On
-        Allow from all
-        Order allow,deny
-    </Location>
+    <VirtualHost *:8080>
+        ServerAdmin rhodecode-admin@localhost
+        DocumentRoot /var/www/html
+        ErrorLog ${'${APACHE_LOG_DIR}'}/error.log
+        CustomLog ${'${APACHE_LOG_DIR}'}/access.log combined
+        Include /home/user/.rccontrol/enterprise-1/mod_dav_svn.conf
+    </VirtualHost>
 
-.. note::
-
-   Once configured, check that you can see the list of repositories on your
-   |RCE| instance.
 
 2. Go to the :menuselection:`Admin --> Settings --> Labs` page, and
    enable :guilabel:`Proxy Subversion HTTP requests`, and specify the
    :guilabel:`Subversion HTTP Server URL`.
 
+3. Open the |RCE| configuration file,
+   :file:`/home/{user}/.rccontrol/{instance-id}/rhodecode.ini`
+
+4. Add the following configuration option in the ``[app:main]``
+   section if you don't have it yet.
+
+   This enable mapping of created |RCE| repo groups into special |svn| paths.
+   Each time a new repository group will be created the system will update
+   the template file, and create new mapping. Apache web server needs to be
+   reloaded to pick up the changes on this file.
+   It's recommended to add reload into a crontab so the changes can be picked
+   automatically once someone creates an repository group inside RhodeCode.

+    ## Enable or disable the config file generation.
+    svn.proxy.generate_config = true
+    ## Generate config file with `SVNListParentPath` set to `On`.
+    svn.proxy.list_parent_path = true
+    ## Set location and file name of generated config file.
+    svn.proxy.config_file_path = %(here)s/mod_dav_svn.conf
+    ## File system path to the directory containing the repositories served by

+    svn.proxy.location_root = /

+
+This would create a special template file called ```mod_dav_svn.conf```. We
+used that file path in the apache config above inside the Include statement.
