> If Mesos is run behind a proxy with a URL prefix e.g.  https://<hostname>:<port>/services/mesos (`/services/mesos` being the URL prefix), sandboxes in mesos don't load. This happens because when
>   Mesos is accessed through a proxy at https://<hostname>:<port>/services/mesos, Mesos tries to request slave state from https://<hostname>:<port>/slave/20151110-232502-218431498-5050-1234-S1/slave(1)/state.json?jsonp=angular.callbacks._4. This URL is missing the /services/mesos path prefix, so the request fails. 
> Fixing this by rewriting URLs in the body of every response, would not be a clean solution and can be error prone.
> After searching around a bit we've learned that this is apparently a common issue with webapps, because there is no standard specification for making them aware of their base URL path. Some will allow you to specify a base path in configuration[1], others will respect an X-Forwarded-Path header if a proxy provides it[2], and others don't handle this at all. 
> It would be great to have explicit support in for this in Mesos.
