Curriclum Mapping Configuration Error

Domain Name "" Does Not Exist In The Database

Curriclum Mapping supports multiple applications from a single database/codebase. It accomplishes this by converting the URL of the client browser Request to a valid ApplicationId in the database table. The following steps describe the process:

1. Web Server Processing
  • When a web server receives a Request from a client browser, it compares the file name extension on the target URL resource to its Application Extension Mappings defined in IIS.
  • Based on the corresponding match, IIS then sends the Request to the defined Executable Path ( aspnet_asapi.dll in the case of ASP.NET Requests ).
  • The aspnet_isapi.dll engine processes the Request in an ordered series of events beginning with Application_BeginRequest.

  • 2. Application_BeginRequest ( globals.asax.vb )
  • The Request URL is parsed based on the "/" character
  • A Domain Name is constructed using each of the relevant parsed URL segments.


    URL: = Domain Name:
    URL: = Domain Name:
    URL: http://localhost/Application/default.aspx = Domain Name: localhost/Application
    URL: = Domain Name:
    URL: = Domain Name:

  • Using the Domain Name, the application queries the database ( Applications table - Domain field ) to locate a matching record.

    Note: If there are multiple URLs which correspond to the same Application then the Domain field must contain each valid Domain Name in a comma seperated list.


    URL: http://localhost/Application/default.aspx
    URL: http://MACHINENAME/Application/default.aspx
    Domain: localhost/Application,MACHINENAME/Application,

    Note: If you are installing the application to a remote server you must modify the Domain field value for the default record in the Applications table according to the rules defined above.
