1. Which ASP.NET configuration options are supported in the ASP.NET implementation on the shared web hosting platform?
   A: Many of the ASP.NET configuration options are not configurable at the site, application or subdirectory level on the shared hosting platform.

The following settings are the only ones that can be changed in your site’s web.config file (s):
   browserCaps
   clientTarget
   pages
   customErrors
   globalization
