At what point in the run-time process does IIS compress output?
<p>I recently tried to integrate <a href="https://github.com/Taritsyn/WebMarkupMin/wiki" rel="nofollow">WebMarkupMin</a>, a run-time html minification library, into my site (C#, IIS 8, MVC 4). We have IIS compression enabled. I discovered that IIS actually compresses the action filter output stream, which means when I try to minify my html in an action filter, I am trying to minify already compressed content.</p>

<p><strong>Question:</strong> At what point in the run-time process does IIS compress output? Is there any way to use mvc action filters to modify html ouptut without disabling IIS compression?</p>
