Applications for Application Dependencies <application>

Overview

The <application> element of the <applicationDependencies> element specifies an application that has dependencies on one or more CGI or ISAPI extension restrictions. Specifically, the groupID attribute of the <application> element specifies the primary application dependency, and the element may contain one or more <add> elements that specify additional dependencies.

Compatibility

	IIS 7.0	IIS 6.0
Notes	The <application> element of the <applicationDependencies> element is new in IIS 7.0.	The <applicationDependencies> element replaces the IIS 6.0 ApplicationDependencies attribute of the IIsWebService metabase object.

Setup

The <application> element of the <applicationDependencies> element is included in the default installation of IIS 7.0.

How To

There is no user interface for configuring the <applicationDependencies> element for IIS 7.0. For examples of how to configure the <applicationDependencies> element programmatically, see the Code Samples section of this document.

Configuration

Attributes

Attribute	Description
groupID	Optional string attribute. Specifies the groupID of the application that has a dependency on an extension restriction. See the following Default Configuration section for the complete list of default values.
Name	Required string attribute. Specifies the unique name of the application that has a dependency on an extension restriction. See the following Default Configuration section for the complete list of default values.

Child Elements

Element	Description
add	Optional element. Adds additional groupIDs to the parent application.
clear	Optional element. Removes all references to additional groupIDs from the add collection.

Configuration Sample

The following configuration sample illustrates the application dependencies in the <applicationDependencies> element for the Default Web Site and the related entries in the <isapiCgiRestriction> after you install Active Server Pages (ASP) and a custom application on IIS 7.0:

• The Active Server Pages application has a dependency on the "ASP" ISAPI/CGI restriction group.
• The custom application has a dependency on the "MyCustomGroup" ISAPI/CGI restriction group, and an additional dependency on the ASP ISAPI/CGI restriction group.

<system.webServer>
   <security>
      <isapiCgiRestriction notListedIsapisAllowed="false" notListedCgisAllowed="false">
         <clear />
         <add allowed="true" groupId="ASP"
            path="C:\Windows\system32\inetsrv\asp.dll" 
            description="Active Server Pages" />
         <add allowed="true" groupId="MyCustomGroup"
            path="C:\Windows\system32\inetsrv\mycustom.dll"
            description="My Custom Application" />
      </isapiCgiRestriction>
   </security>
</system.webServer>

<location path="Default Web Site">
   <system.webServer>
      <security>
         <applicationDependencies>
            <application name="My Custom Application" groupId="MyCustomGroup">
               <add groupId="ASP" />
            </application>
         </applicationDependencies>
      </security>
   </system.webServer>
</location>

Sample Code

The following configuration sample illustrates the application dependencies in the <applicationDependencies> element for the Default Web Site. The custom application has a dependency on the "MyCustomGroup" ISAPI/CGI restriction group, and an additional dependency on the ASP ISAPI/CGI restriction group.

AppCmd.exe

appcmd.exe set config "Default Web Site" -section:system.webServer/security/applicationDependencies /+"[name='My Custom Application',groupId='MyCustomGroup']" /commit:apphost

appcmd.exe set config "Default Web Site" -section:system.webServer/security/applicationDependencies /+"[name='My Custom Application',groupId='MyCustomGroup'].[groupId='ASP']" /commit:apphost

         ConfigurationSection applicationDependenciesSection = config.GetSection("system.webServer/security/applicationDependencies", "Default Web Site");

         ConfigurationElementCollection applicationDependenciesCollection = applicationDependenciesSection.GetCollection();
         ConfigurationElement applicationElement = applicationDependenciesCollection.CreateElement("application");
         applicationElement["name"] = @"My Custom Application";

         addElement["groupId"] = @"ASP";
         applicationCollection.Add(addElement);
         applicationDependenciesCollection.Add(applicationElement);

         serverManager.CommitChanges();
      }
