|
|
// It doesn't look like we need to set this unless it's different
|
|
// than the incoming http request.
|
|
// * `encrypt` - If TLS should be used for the WebSocket connection.
|
|
// we base this on whether or not the protocol is `https`, seems
|
|
// reasonable for now.
|
|
// * `path` - The WebSocket path to use.
|
|
// This apparently doesn't tolerate a leading `/` so we use a
|

// function to tidy that up.
