How enable gzip compression on asphostportal shared windows hosting

I have done research on enabling gzpi compression on asphostportal shared windoes hosting and here is the proposed solution:

 
 <system.webServer>
    <validation validateIntegratedModeConfiguration="false"/>
    <modules runAllManagedModulesForAllRequests="true"/>
    <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">
  <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll"/>
  <dynamicTypes>
    <add mimeType="text/*" enabled="true"/>
    <add mimeType="message/*" enabled="true"/>
    <add mimeType="application/javascript" enabled="true"/>
    <add mimeType="*/*" enabled="false"/>
  </dynamicTypes>
  <staticTypes>
    <add mimeType="text/*" enabled="true"/>
    <add mimeType="message/*" enabled="true"/>
    <add mimeType="application/javascript" enabled="true"/>
    <add mimeType="*/*" enabled="false"/>
  </staticTypes>
</httpCompression>
<urlCompression doStaticCompression="true" doDynamicCompression="true"/>
  </system.webServer>

But this is currently not working and I am not getting http response header, Content-Encoding gzip.

Can someone help me with this? Thanks
