Virtuoso provides a full function web server with dynamic web page generation capability using SQL procedures embedded in HTML or XML via VSP or VSPX. Runtime hosting allows Virtuoso to generate dynamic web pages from other sources also, such as ASP.Net, PHP or JSP.

Out-of-the-box Virtuoso listens for HTTP requests on the port defined in the HTTP Server section of the Virtuoso INI file. The Visual Server Administration Interface is available at this port and can be used to further configure the web server.

Web resources can be based on the file system, reside in the database or in WebDAV or any combination of all of them. WebDAV space can be specified at the path level, by default, paths beginning with /DAV are mapped to the WebDAV root collection (directory) and all other paths are assumed to be file system based. By default / is mapped to the directory specified as ServerRoot in the HTTP Server section of the virtuoso.ini file.

Virtual Directories provide a way to make mappings from paths to other resources such as specific file system or WebDAV locations, other HTTP Servers acting as a proxy or to alter specific processing or authentication rules for a directory.
