Hi!
Cassini does look for index.htm and Default.aspx if default document is not specified when application is registered. If you
contact us via email, then you could send us your app registration settings and/or Fiddler session archive for review.
Our license agreement precludes removing UltiDev branding information, including menu icons. We hope you don't mind that. Hiding an icon would not be real security anyway since users still can simply type http://localhost:7756/.
When registering an app, the easiest way to do it is to pick the default document and then hit Generate button - it will set physical folder location, default document and app ID.
Please let us know if this information was helpful.
Best regards,
UltiDev Team.
