> A few times we've had requests from users who wish to disable browsing of the 
> filesystem in the web UI completely, while keeping other servlet 
> functionality enabled (such as fsck, etc.). Right now, the cheap way to do 
> this is by blocking out the DN web port (50075) from access by clients, but 
> that also hampers HFTP transfers.
> We should instead provide a toggle config for the JSPs to use and disallow 
> browsing if the toggle's enabled. The config can be true by default, to not 
> change the behavior.
