     Hi experts.

    Here is my problem:

    I'm trying to enable GZIP compression on IIS 7.5
    bun no success after hours of googleing.

    I think all the settings are ok

     In ApplicationHost.config I have this httpCompression section:

    <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files" minFileSizeForComp="0">
           <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" />
                 <add mimeType="text/*" enabled="true" />
                 <add mimeType="message/*" enabled="true" />
                 <add mimeType="application/x-javascript" enabled="true" />
                 <add mimeType="application/atom+xml" enabled="true" />
                 <add mimeType="application/xaml+xml" enabled="true" />

    And this urlCompression section:

    <urlCompression dostaticcompression="true" />


    and Here is Failed Request Tracing result:



    Any help would be appreciated
