IIS Gzip压缩拒绝工作

Question

I've looked at every question on this site regarding this issue but none of the solutions worked for me! I know I must be missing something small, but I just can't find it.

I'm using windows 7 and IIS 7.5. So I've added the following to the system applicationHost.config :

 <section name="httpCompression" allowDefinition="MachineToApplication" overrideModeDefault="Allow" />

I've installed Static and dynamic compression and enabled them for the site. And added the following to my web.config

     <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files" >
        <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" doStaticCompression="true"  />
        <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="application/atom+xml" enabled="true" />
            <add mimeType="application/xaml+xml" enabled="true" />
            <add mimeType="*/*" enabled="false" />
        </staticTypes>
    </httpCompression>

But still it does not work. I tried FailedReqLog module to debug this issue but no log files are created. I can't even see httpCompression in my configuration editor in IIS.

I've been trying different solutions for the past 3 days. I'm totally out of ideas. Debugging options are most appreciated if there is a way to trace this issue and see why could it possibly not be following the web.config setting. Even worse why is it not showing it in the configuration editor.

By default on IIS 7.5, if the file size is less than 2,700 KB then compression will not be used. Another exclusion is by CPU utilization. By default, if CPU utilization is over 90%, compression will not be used.

Since this is on your development box, maybe your file sizes are too small. You can change the defaults.
