Manage IIS Settings via ApplicationHost.Config vs. Web.Config

Brass Contributor

I have an IIS setup where multiple websites exist that all share the same document root. Each of the websites have a specific default document though. 

This has been managed in the past by manually editing the applicationHost.config file, adding a section like

<location path="<a href="" target="_blank"></a>">
        <add value="website3-home.html" />


I am trying to script some of this setup, and I am trying to use the WebAdministration powershell module, and am looking at AppCmd, but when I try to set a Default Document setting this way, the setting gets added to Web.Config... and since the websites have a shared document root, they all share the same Web.Config, and this causes a problem.


Is there a way when using WebAdministration or AppCmd to specify that I want the change made specifically in applicationHost.config, not Web.config?


I appreciate any suggestions!

Thanks for the reply Dave;
So, I am looking at the following:


It seems the syntax I want to specifically write the config to applicationHost.config is /COMMIT:APPHOST but I cant seem to figure out the rest of the syntax... keep getting errors:


PS C:\Windows\system32\inetsrv> .\appcmd.exe set config "testsite2" /section:defaultDocument /enabled:true /+files.[value='site2-home.html'] /commit:APPHOST
ERROR ( message:Malformed collection indexer; format is [@position,name='value',name2='value2',...]. The @position specifier is optional, and be '@start', '@end', or '@N' where N is a numeric index i
nto the collection. )
PS C:\Windows\system32\inetsrv>

Might give the quotes a try.

Yep - that did it...

PS C:\Windows\system32\inetsrv> .\appcmd.exe set config "testsite2" /section:defaultDocument /enabled:true "/+files.[value='site2-home.html']" /commit:APPHOST
Applied configuration changes to section "system.webServer/defaultDocument" for "MACHINE/WEBROOT/APPHOST/testsite2" at configuration commit path "MACHINE/WEBROOT/APPHOST"


Thank you so much!! 

Glad to hear, you're welcome.
