>    Affects Versions: 2.1.0
>            Reporter: Zane

> The Spark UI should be accessible behind a gateway that redirects based on the URL path (i.e. http://domain.com/spark --> http://private.domain.com:8080). 
> Currently the Spark UI uses root links in the html page. It would be nice if it used relative links instead. By eliminating the first forward-slash "/" the Spark UI can be accessible behind an HTTP gateway. 
> For example, in core/src/main/scala/org/apache/spark/ui/UIUtils.scala
> {quote}
> ...
> <link rel="stylesheet" href={prependBaseUri("/static/bootstrap.min.css")} type="text/css"/>
> ...
> {quote}
> could be changed to
> {quote}
> ...
> <link rel="stylesheet" href={prependBaseUri("static/bootstrap.min.css")} type="text/css"/>
> ...
> {quote}
> This would allow the Spark UI to be accessible behind a gateway that redirects based on the URL path.
