Portal Configuration Error
Domain Name "www.digitalcommunities.org" Does Not Exist In The Database
Portal 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
||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.
||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: http://www.domain.com/default.aspx = Domain Name: www.domain.com
URL: http://18.104.22.168/default.aspx = Domain Name: 22.214.171.124
URL: http://localhost/Portal/default.aspx = Domain Name: localhost/Portal
URL: http://www.domain.com/virtualdirectory/default.aspx = Domain Name:
URL: http://www.domain.com/directory/default.aspx = 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
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.
