How to fix this?

Rails generates code like this: <link href="/stylesheets/qiushi_handheld_style.css?1179405951" media="handheld" rel="Stylesheet" type="text/css" /> <script src="/javascripts/prototype.js?1179405295" type="text/ javascript"></script>

This code do not work properly in IE6. I want to change the code like this: <link href="/stylesheets/qiushi_handheld_style.css?1179405951.css" media="handheld" rel="Stylesheet" type="text/css" /> <script src="/javascripts/prototype.js?1179405295.js" type="text/ javascript"></script>

How? Thanks.
