Brad Fitzpatrick	5bcac4eaac	net/tshttpproxy: add GetProxyForURL negative cache Otherwise when PAC server is down, we log, and each log entry is a new HTTP request (from logtail) and a new GetProxyForURL call, which again logs, non-stop. This is also nicer to the WinHTTP service. Then also hook up link change notifications to the cache to reset it if there's a chance the network might work sooner.	2020-09-21 14:05:28 -07:00
