Re: NNTP caching proxy



Yep, this is something I've been hoping for. I'd be writing it myself
except I've got enough bloody hacking to do as it is, and news would
be a hell of a protocol to support... ;)

BTW -- something that hasn't been mentioned yet. Most (good)
newsreaders these days use XOVER (the overview mechanism) for browsing
the groups' headers, and only get the articles when they're explicitly
requested.

THIS is where a caching proxy would come in very useful; if the headers
were retrieved by the proxy using XOVER and stored in its own overview
cache, the newsreaders could browse the groups very quickly -- it may
not even be necessary to cache articles AT ALL to gain an appreciable
speedup.

Ah -- who? Sign me up for an alpha, whoever you are! ;)
