Webproxy Plugin
GForge Group developed a proxy plugin for the DSO National Labs in Singapore and they have agreed to release it on gforge.com in source code form so others can use it.
The plugin lets you configure a new tab in your project that captures in content from a separate website. In this case, it was developed to pull WEBGUI content into GForge as a legacy bridge.
You can checkout the code from svn at http://gforge.com/gf/project/webproxy/
