The base url is decided in the file kukit.js, in the function 
kukit.Engine.prototype.calculateBase . It is pretty complicated, and I 
actually have no remembering of neither a description of the supported 
use cases nor a written discussion about it.

As I read from the code it tries to fetch the base in the following order:

1. if there is a link with rel="kss-base-url", it is using the href of 
that as base. This allows a manual override from the template. I cannot 
tell you why/when this is needed or used, since point 2. is meant to do 
exactly the same.

2. if there is a "base" tag in the html, it is using its href. In 
addition it strips the trailing "/" from it, if there is one. This is 
what happens normally, I believe also in your case.

3. If this is not present it uses window.location from javascript.

I hope this helps something, please contact me when you want about this 
issue, I'd try to look at it deeper as well. We may need to improve this 
algorithm to cover the case you are using.

Best wishes
