Universal Messaging supports the concept of plugins that actively process client requests made to nhp and nhps interfaces. There are currently 4 plugins, File (Web Server like behaviour), XML (Browse resources and events in XML), SOAP (Browse channels, queues and events using SOAP protocol) and Proxy Passthrough (Enable http/s requests for specific urls to be forwarded to another host:port).

The plugins are discussed in more detail in the plugins section of this guide.
