ArcGIS Server .NET templates don't work when browser has cookies disabled

Description

ArcGIS Server .NET ADF templates return an application error from client browsers that have disabled cookies.

Cause

When building an application from a template, the web.config file has the following setting:

cookieless="False"

Workaround

• Edit the web.config file of the application and locate the line containing:
  
  cookieless = "False"
  
  Change this value to "True".
  
• As another alternative, configure the client browser to allow cookies. Consult the browser documentation for details.
