# Configure Data Admin to Use the Reverse Proxy

You configure Data Admin to use a reverse proxy by setting the `server.reverseProxy` system property.

When you set `server.reverseProxy` to true, the Data Admin application listens for AJP connections on a port that you can define by using the `server.ajp.port` system property.

In AJP mode, the reverse proxy must translate incoming HTTP(S) connections from your clients into AJP connections to Data Admin. The application reads the user name from incoming requests, so you must set up remote authentication. You cannot encrypt the connection from the reverse proxy to the application.

You can also use a HTTP reverse proxy. You cannot use remote authentication in this mode. Users authenticate by using the proxied login page. However, you can encrypt the connection with SSL.

In both these methods, the reverse proxy must rewrite the request path, response Location headers, and cookie paths.

By default, `server.reverseProxy` is false. In this case, the Data Admin application is available only over HTTP or HTTPS, without a reverse proxy.

## WebSocket Protocol

Data Admin uses the WebSocket protocol to communicate between the user Web browsers and the Java process. Your reverse proxy must tunnel this communication from the client to the application, in addition to forwarding HTTP/AJP requests.

## Set the Reverse Proxy System Property

You can use the following procedure to set the `server.reverseProxy` system property.

To configure Data Admin to use a reverse proxy

- At the command line, send the java run command with the `server.reverseProxy` argument set to `true`. For example:

      java -Dserver.reverseProxy=true -Didol.dataadmin.home=[home directory] -Dserver.port=[port] -jar dataadmin.jar

  By default, this option opens an AJP port on port 8009. To use a different port, set the `server.ajp.port` argument to the correct port number.

  You can also specify the roles to assign to your users by setting the `ida.reverse-proxy.pre-authenticated-roles` system property:

  - Set `ida.reverse-proxy.pre-authenticated-roles` to a comma-separated list of Data Admin Community role names (see User Roles) to use hard-coded role names.

  - Set `ida.reverse-proxy.pre-authenticated-roles` and leave the value blank to use roles from the Community component. For example:

        java -Dserver.reverseProxy=true -Didol.dataadmin.home=[home directory] -Dserver.port=[port] -jar dataadmin.jar -Dida.reverse-proxy.pre-authenticated-roles=

    To use this option, you must ensure that your Community component configuration file has `CheckEntitlement` set to `False` (the default value).

  The default value for this property is `IDAUser`.

  NOTE: This setting does not assign any roles in the Community component. It gives all users that use the reverse proxy the same permissions to access Data Admin.

If you run Data Admin as a service on Windows, you can also add the `server.reverseProxy` property to the `dataadmin.xml` file.

If you run Data Admin as a service on Linux, you can add the arguments to the existing arguments variable in the start scripts (`dataadmin.sh` for SystemV, or `dataadmin.service` for systemd).

When you modify the Data Admin configuration by modifying the XML file or start scripts, you must restart Data Admin to apply your configuration changes.
