I currently have both static and dynamic compression configured. The static compression is working, however the dynamic compression, when checked through YSlow and Fiddler, is not working.
In my applicationHost.config, I have the following settings:
<urlCompression doStaticCompression="true" doDynamicCompression="true"
dynamicCompressionBeforeCache="true" />
<httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files"
maxDiskSpaceUsage="100" minFileSizeForComp="256">
<scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll"
dynamicCompressionLevel="1" />
<dynamicTypes>
<add mimeType="text/*" enabled="true" />
<add mimeType="message/*" enabled="true" />
<add mimeType="application/x-javascript" enabled="true" />
<add mimeType="*/*" enabled="true" />
</dynamicTypes>
<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="true" />
</staticTypes>
</httpCompression>
<serverRuntime frequentHitThreshold="1" frequentHitTimePeriod="01:00:00" />
My web.config has:
<urlCompression doStaticCompression="true"
doDynamicCompression="true" dynamicCompressionBeforeCache="true" />
The modules are installed, and when I use the Failed Request Trace, I get a couple dynamic compression hits, but nothing about success or failure. Just these types of results:
ModuleName DynamicCompressionModule
Notification 536870912
fIsPostNotification false
Notification SEND_RESPONSE
ModuleName DynamicCompressionModule
Notification 536870912
fIsPostNotificationEvent false

fIsPostNotification true
Notification RELEASE_REQUEST_STATE
ModuleName DynamicCompressionModule

fIsPostNotificationEvent true
NotificationStatus 0

I am trying to get my aspx files to compress. Any help would be appreciated. Thanks.
