crypto/tls: Failed handshake should not send any data to client #8720
What does 'go version' print? go version go1.3 windows/amd64 What steps reproduce the problem? Snippet: http://play.golang.org/p/eu_6CStY3k 1. Run the snippet above 2. Browse to http://localhost:8181 What happened? Depending on platform or browser different things might happen. If the browser thinks the data looks binary, it usually starts a download. If the data looks plain-text'ish, it outputs bytes to the browser. What should have happened instead? The connection should have been closed without any data sent, since it doesn't get past the TLS handshake due to protocol mismatch. Or alternatively, a feature specific to net/http using TLS could downgrade the protocol to HTTP and deal with it in some way. Please provide any additional information below. The culprit is the following line: https://code.google.com/p/go/source/browse/src/crypto/tls/conn.go#582 If commented out, it produces the expected "No data received" error on Chrome.
