Tomcat RemoteIpValve would be convenient to use to solve Nuxeo 5.x WebDAV & CMIS Reverse Proxy issues. It might also eliminate the need for the custom nuxeo-virtual-host request header property in the web application.
Unfortunately, RemoteIpValve is only available in Tomcat 6.0.21+ and Nuxeo 5.5 bundles Tomcat 6.0.20. Any plans to upgrade the bundled Tomcat version in the future? Also, any plans to officially support/document RemoteIpValve as a reverse proxy solution?
