> Im wondering if there is a way to configure the OrbeonProxyPortlet to use Basic Authentication.
You should be able to set the following in portlet.xml:
<init-param>
<name>form-runner-url</name>
<value>
http://username:password@localhost:8080/orbeon/</value>
</init-param>
Where you set `username` and `password` to your BASIC auth user information.
This aside, the `oxf.http.proxy.username` and `oxf.http.proxy.password` properties are unrelated to the proxy portlet. They are there to configure an HTTP proxy for Form Runner.
