There is a thread about changing the code to use relative urls in ckeditor to some success.

Everyone else uses one of the 2 the url changer plugins.
So unless you are loading your site from 2 distinct urls and need that to work the plugins will work, they might even let you change to relative urls, in which case it does exactly what you need, i have never used them.
