Enabling gzip compression in Azure App Service

Question

I have a web application hosted in Microsoft azure. Since the local IIS uses compression for both static and dynamic content, I expected this to work on the azure platform as well. Since compression doesn't seem to work, since json and css files, for example, are returned uncompressed:

I tried to set the compression as indicated in the server messages (e.g. gzip compression on or Windows Azure websites ), as this without any changes as a result:

<system.webServer>
    <urlCompression doStaticCompression="true" doDynamicCompression="true" />
  <httpCompression>
    <dynamicTypes>
    <clear />
    <add enabled="true" mimeType="text/*"/>
    <add enabled="true" mimeType="message/*"/>
    <add enabled="true" mimeType="application/x-javascript"/>
    <add enabled="true" mimeType="application/javascript"/>
    <add enabled="true" mimeType="application/json"/>
    <add enabled="false" mimeType="*/*"/>
    <add enabled="true" mimeType="application/atom+xml"/>
    <add enabled="true" mimeType="application/atom+xml;charset=utf-8"/>
  </dynamicTypes>
  <staticTypes>
    <clear />
    <add enabled="true" mimeType="text/*"/>
    <add enabled="true" mimeType="message/*"/>
    <add enabled="true" mimeType="application/javascript"/>
    <add enabled="true" mimeType="application/atom+xml"/>
    <add enabled="true" mimeType="application/xaml+xml"/>
    <add enabled="true" mimeType="application/json"/>
    <add enabled="false" mimeType="*/*"/>
  </staticTypes>
 </httpCompression>
[...]
</system.webServer>

It seems that the azure portal does not allow me to change the compression.

What do I need to do to enable compression, or is this only possible when using Vserver in azure?

web.config:

<system.webServer>
  <urlCompression doStaticCompression="true" doDynamicCompression="true" />
</system.webServer>

:

<httpCompression>
  <dynamicTypes>
    <clear />
    <add enabled="true"  mimeType="text/*"/>
    <add enabled="true"  mimeType="message/*"/>
    <add enabled="true"  mimeType="application/x-javascript"/>
    <add enabled="true"  mimeType="application/javascript"/>
    <add enabled="true"  mimeType="application/json"/>
    <add enabled="false" mimeType="*/*"/>
    <add enabled="true"  mimeType="application/atom+xml"/>
    <add enabled="true"  mimeType="application/atom+xml;charset=utf-8"/>
  </dynamicTypes>
  <staticTypes>
     <clear />
     <add enabled="true" mimeType="text/*"/>
     <add enabled="true" mimeType="message/*"/>
     <add enabled="true" mimeType="application/javascript"/>
     <add enabled="true" mimeType="application/atom+xml"/>
     <add enabled="true" mimeType="application/xaml+xml"/>
     <add enabled="true" mimeType="application/json"/>
     <add enabled="false" mimeType="*/*"/>
   </staticTypes>
 </httpCompression>
