Abstract: A Uniform Resource Identifier (URI) discovery system is implemented that evaluates web configuration servers obtained from web servers to determine the existence and configuration of URIs hosted by the web servers. To discover URIs, the URI discovery system may obtain web server configuration files, and other metadata, from collection agents executing on web servers. The web server configuration files may then be parsed to evaluate the combinations of hosts, paths, and ports for the web server that may correspond to respective URIs. A URI discovery result may then be generated that describes the discovered URIs and includes configurations of the different URIs. The URI discovery result may be stored in an entry for the web server.
