I'm developing a asp.net site (running .net 3.5 SP 1) and using UrlRewriter.Net (<http://urlrewriter.net/>) for urlrewriting.

The site is hostet on a Windows 2003 server with all servicepacks and so forth.

It runs IIS 6.

In order to enable url rewriting I've setup a wildcard handler for \*, which means all requests are sent through the asp.net engine.

I've also enabled IIS compression feature - this works fine when I use the non-rewritten urls.
However it doesn't compress the rewritten pages.

I've added aspx, ashx and asmx as extensions to the metabase.xml, and set the proper compression level (9), etc.

The rewritten pages have .htm extension, so it shouldn't be because the extension is wrong.

Any ideas why this doesn't work ?
