Exposing HTTP/2 and HTTP/3 protocol error details from `SocketsHttpHandler`

Exposing HTTP/2 and HTTP/3 protocol error details from SocketsHttpHandler

This proposal builds on the decisions made in our QUIC Exceptions Design proposal.

Proposed design

  • Define a new exception type ProtocolException, and embed it as HttpRequestException.InnerException
  • Throw ProtocolException directly from HttpResponse content read streams
  • In case of HTTP/3, embed QuicException as ProtocolException.InnerException
