Connect to IDM Through a Proxy Server

To configure IDM to communicate through a proxy server:

Add the following JVM parameters to the value of OPENIDM_OPTS in your startup script (startup.sh or startup.bat):
-Dhttps.proxyHost
Hostname or IP address of the proxy server; for example, proxy.example.com or 192.168.0.1.
-Dhttps.proxyPort
Port number used by IDM; for example, 8443 or 9443.
For example:
```
# Only set OPENIDM_OPTS if not already set
[ -z "$OPENIDM_OPTS" ] && OPENIDM_OPTS="-Xmx1024m -Xms1024m -Dhttps.proxyHost=localhost -Dhttps.proxyPort=8443"
```

Enable the ForwardedRequestCustomizer class so that Jetty honors X-Forwarded- headers.

To enable the class, uncomment the following excerpt in your conf/jetty.xml file:

<Call name="addCustomizer">
    <Arg>
        <New class="org.eclipse.jetty.server.ForwardedRequestCustomizer">
            <Set name="forcedHost">
                <Call class="org.forgerock.openidm.jetty.Param" name="getProperty">
                    <Arg>openidm.host</Arg>
                </Call>:
                <Call class="org.forgerock.openidm.jetty.Param" name="getProperty">
                    <Arg>openidm.port.https</Arg>
                </Call>
            </Set>
        </New>
    </Arg>
</Call>
