Fleur can be asked to listen to a port number. It will then act as a basic HTTP server which will also execute .xqy pages and send back the result. Of course, XForms pages for XSLTForms can be generated by Fleur when executing a .xqy request. It can be used to, for example, provide inline minimal XForms instances which can be interesting for better performance.

This server can process simultaneous requests because of the asynchronous evaluations.
