Hello, Ivan.
Thank you much for the positive feedback.
Current version of UltiDev Cassini does not support multiple applications on the same port, which makes it impossible to register two applications like http://host:1234/app1 and http://host:1234/app2. Since each app has to have its unique port, we didn't implement "virtual folder" feature in UltiDev Cassini (although later we found out that there is another good reason for virtual paths - cookie paths are not port-specific and therefore shared between all apps hosted by Cassini on the same machine).
Virtual folders and port sharing support will be a part of the next release of UltiDev Cassini (which does not have a release schedule yet), but for now the root of your application has to have at least "Bin" folder and "web.config" file. The rest of the files can be placed in a sub-folder inside application's root.
Please let us know if this information was helpful.
Best regards,
UltiDev Team.
