Domain Name sosamamentacao.org.pt Does Not Exist In The Database

DotNetNuke 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.
     
     Examples:
     
     URL: http://www.domain.com/default.aspx = Domain Name: www.domain.com
     URL: http://209.75.24.131/default.aspx = Domain Name: 209.75.24.131
     URL: http://localhost/DotNetNuke/default.aspx = Domain Name: localhost/DotNetNuke
     URL: http://www.domain.com/virtualdirectory/default.aspx = Domain Name: www.domain.com/virtualdirectory
     URL: http://www.domain.com/directory/default.aspx = Domain Name: www.domain.com/directory
   • Using the Domain Name, the application queries the database ( PortalAlias table - HTTPAlias field ) to locate a matching record.
     
     Note: If there are multiple URLs which correspond to the same portal then you can add multiple records to the PortalAlias table pointing to the same portal (PortalId).
     
     Note: If you are installing the application to a remote server you must modify the HTTPAlias field value for the default record in the PortalAlias table according to the rules defined above.
