Compression vs AJAX

I'm trying to use Blowery Web Http Compressing Module (http://www.blowery.org/code/HttpCompressionModule.html), but when i start using it AJAX elements stop working and rise errors. Do anybody know how to get AJAX and blowery compressing module work together.. or just advice another compressing module which can do this work. (it's better if it will be non-commercial module =) )

I've excluded paths written below in webconfig and they start working together!

<excludedPaths>
<add path="ScriptResource.axd"/>
<add path="WebResource.axd"/>
</excludedPaths>
