Brad Fitzpatrick	b026a638c7	net/tshttpproxy: if winhttp.GetProxyForURL blocks too long, use previous value ... We currently have a chickend-and-egg situation in some environments where we can set up routes that WinHTTP's WPAD/PAC resolution service needs to download the PAC file to evaluate GetProxyForURL, but the PAC file is behind a route for which we need to call GetProxyForURL to e.g. dial a DERP server. As a short-term fix, just assume that the most recently returned proxy is good enough for such situations.	2020-09-02 21:15:36 -07:00
