works fime, as it can be configured to support almost any situation..
I dont use RadCompression as it still crocks with SSL, SSL and compression is quite difficult, but the above handles most fine as one can add specific rules to handle the ones where IE crocks..
We use the internal AJAX WebResourceCompression module explictly to do the same thing as RadCompression , the Microsoft module actually works with SSL..
The above two modules do all that we need, application compression and resource.axd compression..
RadCompression has no rules to enable the work around for the standard ssl and/or compression issues most browsers have..
RadCompression defects were reported almost a year ago, and still have not been fixed at last test..
Hope this helps..
