SttpClientException

Known exceptions that might occur when using a backend. Currently this covers:

• connect exceptions: when a connection (tcp socket) can't be established to the target host
• read exceptions: when a connection has been established, but there's any kind of problem receiving or handling the response (e.g. a broken socket or a deserialization error)

In general, it's safe to assume that the request hasn't been sent in case of connect exceptions. With read exceptions, the target host might or might have not received and processed the request.

The SttpBackend.send methods might also throw other exceptions, due to programming errors, bugs in the underlying implementations, bugs in sttp or an uncovered exception.
