Domain Name Microsoft Windows NT 10.0.17763.0 Does Not Exist In The Database

parsan supports multiple portals from a single database/codebase. It accomplishes this by converting the URL of the client browser Request to a valid PortalID in the Portals 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. HttpModule.URLRewrite OnBeginRequest ( UrlRewriteModule.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/parsan/default.aspx = Domain Name: localhost/parsan
      URL: = Domain Name:
      URL: = Domain Name:

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

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


      URL: http://localhost/parsan/default.aspx
      URL: http://MACHINENAME/parsan/default.aspx
      PortalAlias: localhost/parsan,MACHINENAME/parsan,

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