在IIS中压缩OData

Question

I use dynamic compression in IIS7 and enabled the following lines in the configuration:

    <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">
        <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" />
        <staticTypes>
            <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" />
            <add mimeType="*/*" enabled="false" />
        </staticTypes>
        <dynamicTypes>
            <add mimeType="text/*" enabled="true" />
            <add mimeType="message/*" enabled="true" />
            <add mimeType="application/json" enabled="true" />
            <add mimeType="application/json; charset=utf-8" enabled="true" />
            <add mimeType="application/json; odata=fullmetadata; charset=utf-8" enabled="true" />
            <add mimeType="application/x-javascript" enabled="true" />
            <add mimetype="application/atom+xml" enabled="true">
            <add mimetype="application/atom+xml;charset=utf-8" enabled="true">
            <add mimeType="*/*" enabled="false" />
        </dynamicTypes>
    </httpCompression>

I have an OData controller in Web API which is based off a ODataController .

The OData part work fine, but dynamic compression seems not to work on them, the request looks like this:

Accept:application/atomsvc+xml;q=0.8, application/json;odata=fullmetadata;q=0.7, application/json;q=0.5, */*;q=0.1
Accept-Encoding:gzip,deflate,sdch
Accept-Language:en-US,en;q=0.8,nl;q=0.6
Connection:keep-alive

MaxDataServiceVersion:3.0

X-SchemaVersion:2.0.0.265

And the response like this:

Cache-Control:no-cache
Content-Length:34862
Content-Type:application/json; odata=fullmetadata; charset=utf-8
DataServiceVersion:3.0

I suppose the config you posted are web.config of your application. The most easy solution is to changed "add mimeType=" / " enabled="false"" to "add mimeType=" / " enabled="true"" in dynamicTypes of config. You can try if it works.

Another solution is to change the config in IIS manager. you can follow: Here
