It looks like you have to do some extra work to write rules that match
and rewrite all the urls throughout the html, css, _javascript_, etc.
When I build a web application, I am very, very careful to write all
urls so that the application can be moved from one server to another
without breaking. I use an approach I call "dynamic absolute" where
the application dynamically detects its location in the file system
and defines that as a constant for the rest of the application to use,
then determines the proper http/https url, defining that as a constant
as well. Then throughout the application, I use the constants, rather
than literally typed url. The end result is absolute urls.
If you didn't have any part in building the application, I apologize.
I consider problems with urls to be a "code smell", specifically
"Excessive use of literals" (http://en.wikipedia.org/wiki/Code_smell).
Usually, where there is one code smell likely to be many more. So
watch out and good luck!
