I'm running DotNetNuke 4.8.2 on II6.

I followed the steps at http://www.wwwcoder.com/main/parentid/170/site/3669/68/default.aspx to enable compression in IIS6.  I found that these steps worked properly for ASP applications and custom ASP.NET applications that are running on the server, compressing both dynamic asp/aspx files as well as static js/css files.

However, I'm finding that this isn't working properly for DotNetNuke sites - Default.aspx itself is getting compressed (I'm assuming this is due to the Compression module), but the JS, CSS, and AXD files are still getting loaded resulting in total response sizes of over 500kb.  I wrote a small ASP test script that loads a CSS file, and placed it in my DNN site, and neither that ASP page nor the corresponding CSS file were compressed, either.

I looked through the IIS metabase and it doesn't appear that compression is explicitly disabled by the DotNetNuke site.

Any suggestions on next steps I can take on how to debug this or whether this is something that DotNetNuke is blocking somehow?
