How about using a whitespace removal HTTP module? It's simple to implement, clean and reusable...

As with any generic whitespace removal solution though, it can easily introduce errors by removing white space where it is required. It wouldn't take long to give it a try though. :-)

Edited after comments

This will not work with .aspx files out of the box so you'll need to change the context_BeginRequest to the following...

void context_BeginRequest(object sender, EventArgs e)
{
    HttpApplication app = sender as HttpApplication;
    if (app.Response.ContentType == "text/html"
        || app.Response.ContentType == "application/xhtml+xml")
    {
        app.Response.Filter = new WhitespaceFilter(app.Response.Filter);
    }
}
