That's why I don't want to do that.

If I exclude IE from it, I just removed 95% of my possible savings 
because that's what 90% of browsers are using. So, I need to not 
compress images for IE, but compress all text. Then I need to compress 
only HTML for NN4, and everything for all other browsers that accept 
gzip encoding. There is no way to set this up currently.
