Multiple sites in Azure web app - azure

Question

My Azure web app (example.azurewebsites.net) has one custom domain, applicationhost.config:
<sites>
<site name="example" id="111111111">
<bindings>
<binding protocol="http" bindingInformation="*:80:customdomain.com" />
<binding protocol="https" bindingInformation="*:443:customdomain.com" />
<binding protocol="http" bindingInformation="*:80:example.azurewebsites.net" />
<binding protocol="https" bindingInformation="*:443:example.azurewebsites.net" />
</bindings>
<application path="/" applicationPool="example" preloadEnabled="true">
<virtualDirectory path="/" physicalPath="D:\home\site\wwwroot" />
<virtualDirectory path="/iisnodedebugger" physicalPath="C:\DWASFiles\Sites\example\Temp\iisnode" />
</application>
<traceFailedRequestsLogging enabled="false" customActionsEnabled="true" directory="D:\home\LogFiles" />
<detailedErrorLogging enabled="true" directory="D:\home\LogFiles\DetailedErrors" />
<logFile logSiteId="false" />
</site>
...
</sites>
The custom domain's bindigs are automatically added to the default site (example).
I would like to change it, i would like to create a new site with bindings to the custom domain (customdomain.com).
applicationHost.xdt (created with IIS Manager):
<?xml version="1.0" encoding="utf-8"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<system.applicationHost>
<sites>
<site name="example" xdt:Locator="Match(name)">
<bindings>
<binding bindingInformation="*:443:customdomain.com" xdt:Locator="Match(bindingInformation)" xdt:Transform="Remove" />
<binding bindingInformation="*:80:customdomain.com" xdt:Locator="Match(bindingInformation)" xdt:Transform="Remove" />
</bindings>
</site>
<site name="customdomain" id="222222222" xdt:Transform="InsertAfter(/configuration/system.applicationHost/sites/site[(#name='example')])">
<bindings>
<binding protocol="http" bindingInformation="*:80:customdomain.com" />
<binding protocol="https" bindingInformation="*:443:customdomain.com" />
</bindings>
<application path="/" applicationPool="example" preloadEnabled="true">
<virtualDirectory path="/" physicalPath="D:\home\site\wwwroot2" />
<virtualDirectory path="/iisnodedebugger" physicalPath="C:\DWASFiles\Sites\example\Temp\iisnode" />
</application>
</site>
</sites>
</system.applicationHost>
</configuration>
After restart the transform is successfull.
The problem: it has no effect. The customdomain.com is still served from "D:\home\site\wwwroot" and not "D:\home\site\wwwroot2".
After that i deleted only the bindigs without adding the new site, customdomain still working... After that i deleted the whole site (example), example.azurewebsites.net and customdomain.com still working.
Where am I mistaken? Isn't it possible to manipulate the sites section?

Answer 1

May i ask why are you trying to make your life hard?
Why don't you deploy your 2nd application to a new Web App? You can share the same App Service Plan (same VM) if cost is the essence here.
Every Web App has its own custom domain settings which you can configure visually through the Portal:

Answer 2

i did this in the webconfig and it seems to work:
**<rule name="REDIRECT To Site Within a Site" enabled="true" stopProcessing="true">
<match url=".*" />
<conditions>
<add input="{HTTP_HOST}"pattern="^www\.SiteWithinSiteName\.com$" />
<add input="{PATH_INFO}" pattern="^/path/SiteWithinSiteRoot/" negate="true" />
</conditions>
<action type="Rewrite" url="\path\SiteWithinSiteRoot\{R:0}" />
</rule>**
