Server Side Include <serverSideInclude>

Overview

The <serverSideInclude> element specifies whether server-side includes (SSI) #exec directives are disabled for Internet Information Services (IIS) 7.

Specifically, the <serverSideInclude> element contains a single attribute: ssiExecDisable. Setting the ssiExecDisable attribute to true will disable the SSI #exec directive for IIS 7, thereby preventing SSI files from executing programs, scripts, or shell commands on the server.

Compatibility

Note: The cmd directive for #exec is disabled for SSI files in IIS 7; you can only use the cgi directive. For example, you can use the following command with a cgi directive:

<!--#exec cgi="/HITCOUNTER.EXE"-->

But you can no longer use the use the following command with a cmd directive:

<!--#exec cmd="dir /b"-->

If you attempt to use the cmd directive in SSI files on IIS 7, you will receive the following error message:

The CMD option is not enabled for #EXEC calls

Configuration Sample

The following configuration sample disables the #exec command for SSI files in the Default Web Site.

<location path="Default Web Site">
   <system.webServer>
      <serverSideInclude ssiExecDisable="true" />
   </system.webServer>
</location>

Sample Code

The following code samples disable the #exec command for SSI files in the Default Web Site.

AppCmd.exe

appcmd.exe set config "Default Web Site" -section:system.webServer/serverSideInclude /ssiExecDisable:"True" /commit:apphost

Note: You must be sure to set the commit parameter to apphost when you use AppCmd.exe to configure these settings. This commits the configuration settings to the appropriate location section in the ApplicationHost.config file.

C#

using System;
using System.Text;
using Microsoft.Web.Administration;

internal static class Sample
{
   private static void Main()
   {
      using (ServerManager serverManager = new ServerManager())
      {
         Configuration config = serverManager.GetApplicationHostConfiguration();

         ConfigurationSection serverSideIncludeSection = config.GetSection("system.webServer/serverSideInclude", "Default Web Site");
         serverSideIncludeSection["ssiExecDisable"] = true;

         serverManager.CommitChanges();
      }
   }
}
