Re: [privoxy-devel] privoxy 3.0.20 - connection reset by peer

[Ian S. <ian...@fa...>]

Hi Sebastian,

Very glad to hear you sourced the root of the problem!

How strange that it affected only this one site though. I'd be tempted to try to work out why prioritised UDP might affect that site specifically - what is it loading that puts a load on UDP. 

Curious!

Ian
