> If a network issue causes an AM web app to resolve the RM proxy's address to 
> something other than what's listed in the allowed proxies list, the 
> AmIpFilter will 302 redirect the RM proxy's request back to the RM proxy.  
> The RM proxy will then consume all available handler threads connecting to 
> itself over and over, resulting in an outage of the web UI.
