curl: PRE_PROXY change leaks stale Proxy Digest state across proxy-chain boundary

Summary After a Digest-authenticated HTTP proxy transfer, changing only CURLOPTPREPROXY on the same libcurl easy handle does not clear stale proxy Digest/auth state. If the new SOCKS pre-proxy resolves the same HTTP proxy hostname to a different proxy endpoint, the second proxy receives a...

curl: RTSP Digest auth state leaks across origins on reused libcurl easy handle
