[PATCH 0/1] MR8049: winhttp: Add a cache to WinHttpDetectAutoProxyConfigUrl().

[Brendan Shanks (＠bshanks)]

This fixes an issue seen with Steam, which calls `WinHttpGetProxyForUrl()` before pinging WebSocket servers to determine which has the lowest latency. The `WinHttpGetProxyForUrl()`/`WinHttpDetectAutoProxyConfigUrl()` call seems to be included in the timing, and `WinHttpDetectAutoProxyConfigUrl()` taking too long can cause the ping to time out/fail.
