This topic introduces the URLs, URL reservations and registration, default values, and deployment-specific recommendations that you should follow if you create or modify URLs for different server configurations. The following sections are in this topic:

• URLs in Reporting Services
  
• URL Reservation and Registration
  
• Default URLs
  
• Authentication and Service Identity for Reporting Services URLs
  
• URLs for Local Administration
  
• URLs for Scale-out Deployment
  
• URLs for SharePoint Integrated Mode
  

For more information about URL construction and usage in a Reporting Services installation or troubleshooting reservation or registration errors, see Configuring Report Server URLs and Troubleshooting Configuration Errors.

In a Reporting Services installation, you can access the following tools, applications, and items through URLs:

• Report Server Web service
  
• Report Manager
  
• Report Builder
  
• Reports that have been published to a report server
  

Other published URL-addressable items, such as models and shared data sources, should not be accessed through URLs as stand-alone items. The report server does not display those items in a meaningful format when viewed in a browser window.

Note:
This topic does not describe URL access to Report Builder or to specific reports that are stored on the report server. For more information about URL access to these items, see Starting Report Builder and Using a URL to Access Report Server Items in SQL Server Books Online.

A URL reservation defines the URLs that can be used to access a Reporting Services application. Reporting Services will reserve one or more URLs for the Report Server Web service and Report Manager in HTTP.SYS, and then register them when the service starts. URLs to Report Builder and reports are based on the Report Server Web service URL reservation. By appending parameters to the URL, you can open Report Builder or reports through the Web service. Reservations and registration is provided by HTTP.SYS. For more information, see Namespace Reservations, Registration, and Routing on MSDN.

URL reservation is a process by which a URL endpoint to a Web application is created and stored in HTTP.SYS. HTTP.SYS is the common repository of all URL reservations that are defined on a computer and defines a set of common rules that guarantee unique URL reservations.

URL registration occurs when the service starts. The request queue is created and HTTP.SYS begins routing requests to that queue. A URL endpoint must be registered before requests that are directed to that endpoint are added to the queue. When the Report Server service starts, it will register all URLs that it has reserved for all enabled applications. This means that the Web service must be enabled in order for registration to occur. If you set the WebServiceAndHTTPAccessEnabled property to False in the Surface Area Configuration for Reporting Services facet of Policy-Based Management, the URL for the Web service will not register when the service starts.

URLs are unregistered if you stop the service or recycle the Web service or Report Manager application domain. If you modify a URL reservation while the service is running, the report server will recycle the application domain immediately so that the old URL can be unregistered and the new one put into use.

A few simple examples illustrate the concept of a URL reservation and how it relates to URL addresses used for Reporting Services applications. A key point to notice is that the URL reservation has different syntax than the the URL you use to access the application:

URL Reservation in HTTP.SYS	URL	Explanation
http://+:80/reportserver	http://<computername>/reportserver http://<IPAddress>/reportserver http://localhost/reportserver	The URL reservation specifies a wildcard (+) on port 80. This puts into the report server queue any incoming request that specifies a host that resolves to the report server computer on port 80. Notice that with this URL reservation, any number of URLs can be used to access the report server. This is the default URL reservation for a Reporting Services report server for most operating systems.
http://123.45.67.0:80/reportserver	http://123.45.67.0/reportserver	This URL reservation specifies an IP address and is much more restrictive than the wildcard URL reservation. Only URLs that include the IP address can be used to connect to the report server. Given this URL reservation, a request to a report server at http://<computername>/reportserver or http://localhost/reportserver would fail.

If you install Reporting Services in the default configuration, Setup will reserve URLs for the Report Server Web service and Report Manager. You can also accept these default values when you define URL reservations in the Reporting Services Configuration tool. Default URLs will include an instance name if you install SQL Server Express or if you install Reporting Services as a named instance.

Important:
The instance character is an underscore character (_).

URL reservations include a port number. The following operating systems will allow multiple Web applications to share a port: Windows Server 2003, Windows Vista, and Windows Server 2008. If you are using Windows XP, make sure to use unique ports.

Instance Type	Application	Default URL	Actual URL reservation in HTTP.SYS
Default instance	Report Server Web service	http://<servername>/reportserver	http://<servername>:80/reportserver
Default instance	Report Manager	http://<servername>/reportserver	http://<servername>:80/reportserver
Named instance	Report Server Web service	http://<servername>/reportserver_<instancename>	http://<servername>:80/reportserver_<instancename>
Named instance	Report Manager	http://<servername>/reports_<instancename>	http://<servername>:80/reports_<instancename>
SQL Server Express	Report Server Web service	http://<servername>/reportserver_SQLExpress	http://<servername>:80/reportserver_SQLExpress
SQL Server Express	Report Manager	http://<servername>/reports_SQLExpress	http://<servername>:80/reports_SQLExpress

Reporting Services URL reservations specify the service account of the Report Server service. The account under which the service runs is used for all URLs that are created for the Reporting Services applications that run in the same instance. The service identity of the report server instance is stored in the RSReportServer.config file.

The service account has no default value. However, specifying a service account is required during Setup and is specified in URLReservation in RSReportServer.config even if you install the server in files-only mode. Valid values for the service account include a domain user account, LocalSystem, or NetworkService.

Anonymous access is disabled because the default security is RSWindowsNegotiate. For intranet access, report server URLs use network computer names. If you want to configure Reporting Services for Internet connections, you must use different settings. For more information, see Planning for Extranet or Internet Deployment. For more information about authentication, see Configuring Authentication in Reporting Services.

You can use http://localhost/reportserver or http://localhost/reports if you specified a strong or weak wildcard for the URL reservation.

The http://localhost URL is interpreted as http://127.0.0.1. If you pegged the URL reservation to a computer name or single IP address, you cannot use localhost unless you create an additional reservation for 127.0.0.1 on the local computer. Similarly, if localhost or 127.0.0.1 is disabled on your computer, you cannot use that URL.

Windows Vista and Windows Server "Longhorn" include new security features to minimize the risk of accidentally running programs with elevated privileges. Additional steps are necessary to enable local administration on these operating systems. For more information, see How to: Configure a Report Server for Local Administration on Windows Vista and Windows Server 2008.

If a stand-alone report server is configured to run within a larger deployment of a SharePoint product or technology, URL and virtual directory construction will be affected in the following ways:

• URLs for reports and other items are addressed through the SharePoint Web application URL. For URL access to specific reports, always use a fully qualified URL that includes the site path, the document library, the item name, and a file name extension (such as .rdl for a report). You must specify fully qualified URLs when you reference shared data sources and models in reports, and when you specify a target server and folders for publish operations to a report server.
  
• The file name extension is used to distinguish between different types of report server items. Valid extensions include .rdl for report definitions, .smdl for report models, and .rsds for shared data sources that are created for a SharePoint site.
  
• Although SharePoint products and technologies have URL reservations defined for them, you can ignore the reservation when publishing to the server. For SharePoint Web applications, URL reservation is an internal operation.
  
• For single server deployments where an integrated report server and SharePoint technology instance are installed on the same computer, you cannot use http://localhost/reportserver. If http://localhost is used to access the SharePoint Web application, you must use a non-default Web site or a unique port assignment to access a report server. Furthermore, if the report server is integrated with a SharePoint farm, localhost access to a reports server will not resolve for nodes in the deployment that are installed on remote computers.
  
• The URL reservation and endpoint for Report Manager cannot be configured for a report server that runs in SharePoint integrated mode. If you do configure it, it will no longer work after you deploy a report server in SharePoint integrated mode. Report Manager is not supported in this mode.
  

If you integrated a report server scale-out deployment to run within a larger deployment of a SharePoint product or technology, load balance the report server nodes and define a single virtual server URL to the scale-out deployment. Report Server integration settings only allow you to specify a single report server URL. In the case of a scale-out deployment, the URL must be the access point for the server nodes in the scale-out deployment.
