I just can't seem to get GZIP compression enabled for my ASP.NET 4 application. Only javascript files seem to get compressed. The page, css and others dont get compressed.
The response header of a not compressed CSS file is:
Content-Type text/css
Last-Modified Mon, 09 Aug 2010 20:10:34 GMT
Accept-Ranges bytes
Etag "5d71bdecfe37cb1:0"
Server Microsoft-IIS/7.5
Date Sat, 28 Aug 2010 14:33:56 GMT
Content-Length 3364
And for a Javascript file that gets compressed (scriptresource.axd):
Cache-Control public
Content-Type application/x-javascript
Content-Encoding gzip
Expires Sun, 28 Aug 2011 14:33:50 GMT

Content-Length 478
In applicationHost.config:
<httpCompression sendCacheHeaders="false" directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files" noCompressionForRange="true">
<scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" />
<staticTypes>
</staticTypes>
<dynamicTypes>
</dynamicTypes>
</httpCompression>
And in the app web.config:
<urlCompression doStaticCompression="true" doDynamicCompression="true" dynamicCompressionBeforeCache="true" />
<httpCompression noCompressionForRange="false" noCompressionForHttp10="false" noCompressionForProxies="false" >
<dynamicTypes>
<add mimeType="text/css" enabled="true" />
</dynamicTypes>
<staticTypes>
<add mimeType="text/css" enabled="true" />
</staticTypes>
</httpCompression>
Can anybody tell me what setting I am missing?
