I found a much easier way to do this. Instead of selectively doing your own compression, you can selectively disable the default IIS compression (assuming its enabled in your web.config).

Simply remove the accept-encoding encoding header on the request and IIS wont compress the page.

(global.asax.cs:)

protected void Application_BeginRequest(object sender, EventArgs e)
{
    try
    {
        HttpContext.Current.Request.Headers["Accept-Encoding"] = "";
    }
    catch(Exception){}
}
