# Reverse Proxy Configuration

The automatic hostname, protocol or webroot detection of ownCloud can fail in certain reverse proxy situations. This configuration allows to manually override the automatic detection.

## Parameters

If ownCloud fails to automatically detected the hostname, protocol or webroot you can use the overwrite parameters inside the `config/config.php`. The overwritehost parameter is used to set the hostname of the proxy. You can also specify a port. The overwriteprotocol parameter is used to set the protocol of the proxy. You can choose between the two options http and https. The overwritewebroot parameter is used to set the absolute web path of the proxy to the ownCloud folder. When you want to keep the automatic detection of one of the three parameters you can leave the value empty or don’t set it. The overwritecondaddr parameter is used to overwrite the values dependent on the remote address. The value must be a regular expression of the IP addresses of the proxy. This is useful when you use a reverse SSL proxy only for https access and you want to use the automatic detection for http access.

## Example

### Multiple Domains Reverse SSL Proxy

If you want to access your ownCloud installation http://domain.tld/owncloud via a multiple domains reverse SSL proxy https://ssl-proxy.tld/domain.tld/owncloud with the IP address 10.0.0.1 you can set the following parameters inside the `config/config.php`.

    <?php
    $CONFIG = array (
      "overwritehost"     => "ssl-proxy.tld",
      "overwriteprotocol" => "https",
      "overwritewebroot"  => "/domain.tld/owncloud",
      "overwritecondaddr" => "^10\.0\.0\.1$",
    );

Note

If you want to use the SSL proxy during installation you have to create the `config/config.php` otherwise you have to extend to existing $CONFIG array.
