I noticed that if i link a js file through the http, like
<script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js" type="text/javascript"></script>
it’s size 32.9kb.
However when i download it the size became 110kb…

Is there anything to do with this?
My OS is win 7 64bit.
I believe windows could change file size according to it’s file system, but that much?
The first one is gzipped while the second one isn’t
