[Handle-info] Re: updating resolver cache

[Scott Yeadon <scott.yeadon@anu.edu.au>]

Hi,

Sorry, I should have added some context to this. We won't know whether a 
handle value will be frequently changed, however if it is we want to 
avoid a situation where, for example, someone moves their research 
paper, updates their handle and the change isn't reflected in the proxy 
resolution quickly and leads to "handle not found" errors. I could lower 
the TTL for all handle values to a low value but a) is that a sensible 
approach given that I imagine most handles won't change frequently and 
b) what other options do I have to "force" an update in the global proxy.
