Sandbox

What

When a request is denied or AWS SigV4 re-signing fails, the proxy now destroys the client socket and, if the original socket is a different one, fails that too, instead of leaving a half-open connection.

Details
  • Separately, if an incoming request declared a body but neither content-length nor transfer-encoding survives into the outbound headers, the proxy sets transfer-encoding: chunked.
Evidence

AWS SigV4 re-signing failed:

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
