I saw on jQuery UI site such line in source code:
<script src="http://jquery-ui.googlecode.com/svn/tags/latest/external/jquery.bgiframe-2.1.2.js" type="text/javascript"></script>
Looks like they host there static files on google servers to save their server resources.
It's very interesting. I haven't found usefull descriptions from googlecode.com.
So, is it possible for me to do the same with my site static files fo free?
Just upload your files to a Google Code repository and you'll be able to find a direct link to the raw files.
