Notebook base_url configuration always keeps "/" even when configured with empty string

Hi,

I am trying to make the html and other served files by the notebook relative to the entire path. However, the base_url configuration always results on the notebook serving files with "/" as the first character. The html code below is the result of using jupyter notebook --NotebookApp.base_url=""

<link rel="stylesheet" href="/static/components/...
    <link rel="stylesheet" href="/static/components/...

I would like to know if there is a work around for this problem, or if there is another way to make relative to the entire path. My final objective would be serving jupyter with reverse proxy.
